## Description

desertcart.com: JOYO Amp Simulator Guitar Pedal, 9 Amp Models with Dual Channel & 18 Tones, IR Cab Sim, XLR Out & FX Loop, Bypass (Preamp House R-15)

Review: Versatile, Great-Sounding Preamp with an Excellent Effects Loop - I’ve been building a pedalboard around the idea of having a real “amp” at the center of it, and the Joyo Preamp House has exceeded my expectations. The biggest selling point is obviously the variety of amp models. There are plenty of great tones to explore, but what really impressed me is that the clean and dirty channels on each model are genuinely useful. I settled on the Friedman model almost immediately because both channels sound great. The clean channel adds life and dynamics without feeling sterile, and the dirty channel has enough gain for hard rock while still taking a Tube Screamer beautifully if I want to tighten things up. This was also my first experience using an effects loop, and I didn’t expect it to make as much of a difference as it did. Moving my modulation, delay, and reverb into the loop made everything sound clearer and less muddy, especially with higher gain sounds. It honestly changed the way I think about my pedalboard. The pedal itself is easy to use. Switching between the clean and dirty channels is simple, and once I got my presets dialed in, it fit perfectly into my setup. If I could change two things, they would both be related to the footswitches. First, it’s very easy to accidentally overwrite a preset. I’d much rather have to hold the footswitch for about three seconds instead of one before it saves. Second, I wish there were a dedicated bypass instead of having to press both footswitches at the same time to turn the pedal off. Neither of these are deal breakers, they’re just small usability improvements. Overall, this is one of those rare pieces of gear that actually solved the problem I bought it to solve. It made my clean tones more inspiring, gave me a great high-gain channel, and even improved the way the rest of my pedals sound thanks to the effects loop. For the price, it’s an incredible value, and I’d absolutely recommend it to anyone looking for a versatile preamp pedal.
Review: Nice preamp sounds amazing when settings are right - Alright got my Joyo preamp house R-15 series and it makes great sounds. However I have three different amps and one combo amp which is what I used to make the video today. I will start by mentioning that the pedal doesn’t work well with all amplifers guessing that you have to try yours out to get the idea of wether you like it or not. So anyway any brand names mentioned in my video post is not for any commissions nor advertising purposes. Now the pedal has nice quality knobs and buttons as well as plugins seems nice and sturdy not a cheaply made product. It’s easy to use and setup your programmed settings for each model on the pedal not difficult to use at all . I’ve not used the pedal connected to any computer but only to amplifier and the guitar. Left side button controls clean channels right side button controls the distortion channels -Programming- example: switch on your amp model on distortion side model 2 -Then set your tone knobs and volume level when you’re done and happy with the settings sounds -press down the distortion channel button and hold down until the led lights blink,when light stops blinking its saved for that model -now here’s where I think people are getting confused, if you turn on your pedal switch it the model that has been set from last time it will continue to play those same settings you did -but if you turn any of the knobs it loses the saved settings so remember this and you will need to start over again and set once more All models clean and distortion channels are done the same way as I mentioned above So far every amplifier model on the pedal sounds great but I think some of them are just a little plucky like bassy and too much treble no matter what your set at on the pedal You also have to make adjustments on your amplifier tones as well so don’t forget that part And that’s the part that I don’t like about it I’m guessing all pedals do that but to me it’s annoying and makes things way off one way or another. Back to the sounds from the pedal, like I said it creates awesome tone and sounds alot like what they’ve simulated here on the pedal. So if you want that big MB its here If you want that nasty Marsh it’s here And thats all I can say. Now in my video I mention its getting very warm to hot in around 5-10 minutes after play and I don’t know why either because it’s connected just as instructed by the manual So I’ve contacted the seller at Joyo and they’re working with me to help out. My guess is this one is defective because there’s nothing wrong with any of my equipment as far as that goes. I will update more on how things turn out later on Get one of these you will be amazed by the simulation of amps on here

## Features

- 9 AMP MODELS × 2 CHANNELS = 18 TONES IN ONE PEDAL: The Preamp House delivers nine meticulously voiced preamp models—from vintage American clean (65Twin) to British crunch (JCM900), chimey Class A (AC30), boutique American drive (LONESTAR), modern high-gain (DUAL RECTIFIER, 5150Ⅲ, POWERBALL), and signature rock tones (TH200, BE100). Each amp features a dedicated Clean channel and Distortion channel, giving you 18 distinct tones ranging from pristine cleans to aggressive modern metal. Players describe it as an "excellent modeling preamp" that's "WAY exceeded my expectations."
- DUAL CHANNEL WITH SAVABLE PRESETS — ONE CLEAN, ONE DIRTY: The two footswitches let you toggle between a Clean channel and a Distortion channel for each amp model. Hold either footswitch to save your current settings—one clean preset and one distortion preset can be stored at a time. Note: The Preamp House stores one clean tone and one distortion tone globally; switching to a different amp model will load that model's last-saved settings. Plan your two presets around your most-used tones for seamless live switching.
- BUILT-IN IR CAB SIM, XLR OUT, FX LOOP & HEADPHONE OUTPUT: The integrated 4×12 impulse response cabinet simulation (Celestion-voiced) can be toggled to the XLR output, the 6.35mm output, or both—giving you a consistent, mix-ready tone for any setup. XLR balanced output with Ground Lift connects directly to PA systems or audio interfaces. The built-in FX Loop lets you place modulation, delay, and reverb effects after the preamp for proper signal routing. A 3.5mm headphone jack enables silent practice anytime.
- AMBIENT LED LIGHTING & ROAD-READY R SERIES DESIGN: The iconic ambient LED lights on the front and rear edges bring a professional, futuristic edge to your pedalboard. Choose from 3 modes (Sync, Always On, or Off) via a recessed switch on the underside. Encased in a rugged aluminum alloy chassis (130×110×50mm, 450g), the Preamp House features two sturdy metal footswitches and smooth, responsive knobs. Bypass mode is engaged by pressing both footswitches simultaneously.
- JOYO QUALITY & AFTER-SALES CONFIDENCE: Backed by JOYO's decade-plus reputation for crafting innovative, budget-friendly gear. Important: Powered by 9V DC adapter only (center negative, not included). Rated current: 400mA—this pedal requires high current and cannot run on a 9V battery. For the cleanest sound, use a regulated, isolated 9V power supply with at least 500mA output. Note: Ensure XLR phantom power is OFF on your mixer or interface before connecting—phantom power can damage the pedal. Should any issues arise, our dedicated support team is ready to assist through your desertcart order page.

## Questions & Answers

**Q: Why is my pedal producing noticeable hum, buzz, or unexpected background noise?**
A: Digital pedals require clean power. Ensure you use an isolated, regulated 9V DC center negative power supply delivering at least 400mA. Avoid non-isolated daisy chains. If connected to a mixer, try toggling the GND/LIFT switch.

**Q: Does the R-15 include a power adapter?**
A: No, the power adapter is not included. It requires a 9V DC center-negative adapter. No battery compartment—adapter only. Isolated power supply recommended for cleanest performance.

**Q: Can I connect the XLR output straight to a mixer or PA?**
A: Yes! Set CAB SIM to XLR:ON and plug in via XLR. Crucial: ensure 48V phantom power on that mixer channel is switched OFF before connecting to avoid circuit damage. Flip the LIFT switch if ground loop hum appears.

**Q: How do I store a modified tone setting to a channel?**
A: Turn any knob to shape your sound (channel LED will flash). To lock settings, press and hold that channel's footswitch until the LED stays solid. If not saved, your adjustments remain active until you switch channels.

**Q: How do the three CAB SIM switch modes work?**
A: OFF disables cab sim on both outputs. XLR:ON/6.35:OFF routes cab sim to PA via XLR while sending raw preamp to your stage amp. XLR:ON/6.35:ON activates 4x12 cab sim across both 1/4" and XLR connections.

### ⭐⭐⭐⭐⭐ JOYO PREAMP HOUSE IS A WINNER
*by M***G on December 5, 2020*

I'm a big fan of Joyo pedals and this one does not disappoint, I got it on sale and I'm delighted about the price. What is Preamp House? It's a two channel programmable preamp with one channel voiced clean and one voiced dirty. The instructions are not good but after reading them and a bit of experimenting the Preamp House delivered the goods for me. You use the controls to set up and create your clean sound, then press and hold the clean channel selector footswitch to store the sound in the clean channel position. Then repeat the process for the distortion channel, press and hold to store the sound. You're now ready to play. A three position toggle switch controls where the single cab IR is implemented, it can be off or on and the switch allows you to put it on the 1/4" output, the XLR output or both outputs. The single IR is a 4x12 loaded with Celestion speakers, fortunately for me that is my favorite cab configuration. The IR adds a lot of low-end fullness and reduces high frequency fizz on distorted tones. A single mono effect send and return loop is located prior to the main output. I'm currently running a Joyo "Atmosphere" reverb effects pedal in the loop and it sounds great. The "Clean" channel sounds really great, the Fender models are my favorite but there are many great tones available. The "Dirty" channel can really crunch and sing, the EVH voice is outstanding, I like all the dirty sounds and have had a lot of fun experimenting with them. A favorite feature is how the Dirty channel gets cleaner as you turn down the guitar driving the Preamp House. I've done most of my playing and testing of the Preamp House pedal using a Gibson SG and a Line6 Variax Standard guitar. Clean acoustic guitar sounds are full and rich, crunchy sounds easily go from Clapton to AC-DC to Stones and even Black Sabbath. One caution, the Joyo Preamp House requires more current than a 9-volt battery can provide. I tried a brand new Duracell 9-volt and it would make the lights light up but the pedal produced no audio. When I powered the pedal with a 500ma power supply output I was rewarded with big rich sound. (Hint: the Joyo Atmosphere pedal also likes more current than a 9-volt battery can deliver). I personally like this Joyo Preamp House pedal much better than the more expensive SansAmp or Strymon Iridium. While the Iridium allows more IR capability it does not have an effects loop nor channel switching nor the ability to store your settings. The overall build quality on the Joyo Preamp House is excellent. The metal work is heavy duty and all the controls feel good and solid, the pots are smooth without any scratchiness. The paintwork, nomenclature and silk screening are all very high quality as well. The Joyo Preamp House turns my little battery powered Bose S1 FRFR speaker into a fire breathing Marshall or a Fender Deluxe Reverb or something in-between, I could easily gig with this combination and be happy with the dynamics and tone. The Joyo Preamp House WAY exceeded my expectations and fulfills a need. It allows me to play rock guitar without dragging along a dedicated guitar amp. The XLR output can drive a PA system direct while the 1/4" output can drive a stage monitor amp like my Bose S1 or I can turn off the IR on the 1/4" output and plug into one of my Marshall combo amps. Preamp House is a great pedal, great tones, great features and a great price. Good luck and good music to all!
