since I heard of amp in a box (pedal style) stuff, I've wanted to get my hands on one of those to make small gigs easier (not having to carry amp and cab). Before the Simplifier DLX was even there, I got a very affordable AC 30 style pedal (it was fine actually) early in 2020 right before Covid hit and live shows were no more for a while and I forgot about the whole thing.

Then a couple of months ago I stumbled upon the Simplifier DLX by coincidence while browsing Thomann and man I was so impressed and wanted to try it! and its features seem more appealing than one of another very popular choices (which is still great but I'm glad I didn't get that one) since the DSM has an FX loop and more routing options plus it's analog. Anyway long story short I've received it a week ago and I'm still blown away by the quality of sound and how tube like it feels and responds! It's really a piece of art and inspires a lot! all 3 amp models are amazing, and it takes pedals really really well (tried it with TC Rusty Fuzz, Tube Screamer Mini, and a Wampler Triple Wreck) plus a TC Plethora in the loop and it sounds phenomenal! build quality is great! the cab sim is really convincing although you can use the unbalanced out and bypass the internal CAB sim to use your own CAB IRs if you wish and it delivers great too! Oh and it's handmade and hand signed!! which is a nice thing too!

All in all, it's a well engineered piece of gear!


Great sound and flexibility
Robert Attard 18.06.2021
I am super happy with this analog pedal sized dual amplifier especially after getting familiar with its functions and the possibilities it offers. This is coming from a guy who proudly owns a Kemper. When it comes to this type of solution I think the playing 'feel' I get from this pedal takes me closer to a real amp. The dynamic range of this thing is amazing.
Pedals work fantastic with this device. Be mindful of proper gain staging when using pedals. I am really having fun playing with this thing.

Setups that I tried
DLX => ID22 interface => mac => FRFR monitors
DLX => JOJO BlueJay amp => Vox cabinet
DLX (cab sim off) => Kemper (amp off, cab on) => amp (return) =>cab
The DLX sounds great with headphones (I am using the AKG K712) which makes it also a perfect practice tool.

- Very good sound that feels very responsive. Dynamic range is amazing for this kind of solution.
- Endless routing possibilities
- Super easy and straight forward interface.
- Takes pedals really well (seriously)
- Blending between the two amp channels creates a lot of possibilities. Amp channels offer the same amp models but are still different from each other.
- pricing is just right for this level of quality.
- compact size means you can take it anywhere.

- The small knobs are slightly wobbly.
- Manual lacks depth. I want to read more about it!
- Reverb is 'ok' but then again you can plug in your favourite reverb pedal in the send/return of the pedal.
- stereo Spread function is non adjustable and tires me after a while (too much phase shifting)


A small MAGIC box!
SOK314 16.01.2023
It's incredible the things that little preamp can do: 2 separate channels, a footswitch, integrated reverb, FX loop, MANY MANY controls and the possibility of routing it stereo through balanced XLR outputs straight to my monitor speakers. All in a 20x15 cm box, so it easily fits on my small pedalboard and I can bring it wherever I want. For me, a game-changer!


This little box is awesome

I love the box. It sounds so good and lively, and it's feature packed to shape your tone in various ways. I'll share one little gotcha that might save you some time. Use a good quality power supply. I found that the DLX is susceptible to humming otherwise. On that note, I know this is nitpicking but they could have provided a power supply adapter. Also, my box isn't sitting perfectly flat, but wobbles a tiny bit. No biggie and can probably be solved by putting on rubber feet, which again would have been nice if it was included. Other than that, it's everything I wanted it to be. Many options for routing the signal, parallel amps, parallel cabs, send and return for fx loop, stereo xlr output. Superb really.
