DSM & Humboldt Simplifier DLX Amp/Cab Sim 5-stars Reviews

A versatile and quality device, made with care

18 knobs +18 switches... and it's called Simplifier?

Don't be fooled by the overwhelming number of knobs and switches. It's simply two guitar preamps in one box. If you've played with guitar amps, effects loops, and cabinets, you're already familiar with all the parameters you can tweak.

Signal routing: best among competition

This is where I had to spend a few minutes playing with the options. The routing possibilities this unit offers are astounding: single/dual/stereo channels combined with dual/stereo effects loop options and all the outputs you need to connect your amp or stage monitor and PA at the same time. It covers any signal configuration in both the stage and at home.

Excellent sound quality

You will notice this even before you learn how to properly operate the unit. It's not complicated to make it sound good. Unlike other similar solutions, there are no "sweet spots" you have to find to get the right sound. No. It sounds good with almost any combination, because all those knobs are there to help you "build" your sound. And because it's full analog, you can forget about latency issues. Well, the reverb module is digital, but works in parallel so there are no latency issues here. Plus, it's also really good.

Great pedal. I've been using it for 5 months and it hasn't let me down in the slightest.

DSM & Humboldt Simplifier DLX Amp/Cab Sim

Best Analog Amp And Cab Simulator. Awesome Features. Takes Pedals Very Well

A small MAGIC box!

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!

Exceptional piece of gear

Whenever I show this to friends, they are more often than not taken aback by the apparent complexity of the thing, however, do not be deceived. The amount of knobs is simply due to the fact that there are 2 channels (duplicated top row of knobs) and then L & R amp & cab sims (duplicated bottom row of knobs), so in essence you will more often than not be using only half the knobs at any given moment.

Of course, it's still quite an impressive amount of options, and on the sides there are a dozen further features and bypass options, but everything is appropriately labelled so it's very easy to know what you are doing. The construction feels solid.

It is simply amazing how much stuff they managed to cram into this small box. I was spending forever trying to find a nice small amp and loadbox and cabsim to handle it all in a small apartment, but thanks to this marvel of engineering I can sell all of that and just use this alone to get my tones. And thanks to the 3 different pre amp options, 3 different power amp tube options, 3 different cabs and the Resonance and Presence knobs, this thing has tone for DAYS.

If you have a small apartment, this is a godsend.

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.

Sounds Ace!

Blown away by how good this sounds, and how it's simplified my practice/gig pedalboard.

Great sound and flexibility

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.

Pros:

- 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.

Cons:

- 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)
