DSM & Humboldt Simplifier DLX Amp/Cab Sim

Lots of functionality and good tones

The product has lots of functionality, with endless options for achieving the exact tone that you want.

You can output the sound through headphones, speakers, a PA system, and more. There are also lots of options for configuring things such as effects loops, bypass, etc.

The quality feels reasonable, but less sturdy than other pedals such as Boss, Strymon and EHX. For this price point, I would have expected a little more so that I could be reassured by the longevity.

The headphone out is okay, but the sound is not amazing and seems like it clips. But fine for casual home practice.

It can be a bit overwhelming at first and the manual is not very clear in some areas, but you can begin to unlock some of its potential with some tweaking and a little time.

Overall, this pedal is very unique with lots of flexibility, but I can only hope that they address some of the smaller issues in a future iteration.

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.

Great features ...poor quality

This Item has been in for repair twice. Presently waiting for the outcome of the second repair, it lasted 15mins after the first repair before a new fault appeared.

A regrettable purchase. Wish I'd returned it within the 30-day money back period.

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!

Build quality needs improvement

This unit has unrivalled features for the price and size as well as remarkable flexibility, but after 3 months it was developing faults and after 9 months had to be returned. I'm now without it for nearly a month while it's been sent for repair.

I was using the DLX in a parallel amps config with the stereo fx loop going out via the XLRs to my audio interface. The sound quality was fantastic. Everything from sparkly cleans to heavy overdrive can be handled by this unit. The 'Marshall' tones are huge.

But, there's a but. A big one. When I opened the DLX box and took the unit out for the first time, one of the retaining nuts for a mini toggle switch fell off. Every other retaining nut was very loose and the toggle switches could be depressed simply by touching them lightly. I had to tighten them all before even powering the DLX up. I was concerned I might get an electric shock if I powered the DLX on in the condition I received it.

3 months later the red channel began playing only intermittently. Shortly after, it was only producing low volume scratchy distorted output regardless of amp model and gain setting. Shortly after that it would only output a 100% wet reverb signal, even when reverb was disabled.

So the DLX I received was in no state to be sent to a customer. The build quality may actually have been dangerous as well as inadequate. And I'm back to having to use and lug an amp around while I wait for it to be repaired. Exactly what I hoped to avoid when I bought the DLX.

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.

It's all about the sound.

A vast array of usable sounds from clean to overdriven with a myriad of nuanced variations. Need stronger reading glasses for optimum selections.
