Hey everyone, I wanted to take some time to write about my experiences with the Simble Overdrive. I wanted to do this so that anyone who may be curious about this pedal will have a basic idea about whether this pedal will suit their needs. Before I dive into the details about the pedal, I want to state that I tried this pedal with three different guitars, which were an American Nitro Strat, a Gibson ES-339 Studio, and an Epiphone SG/G-400 which has BG Pure90 pickups. The amp I did the demo through was a Bugera V22. Before engaging the pedal, I took some time to dial in the clearest clean tone for each guitar so that the Simble had the best possible clean platform to work with. Before purchasing the Simble, I had read a lot about it on various forums and hear many YouTube videos of different people demoing the pedal. I thought it had a lot of potential and at the price range of $189, it would be a hard one to beat. I got lucky enough to score one off Craigslist for around $100, which to me was a steal. When I took the pedal home and opened the box, I saw that the guys from Mad Professor included some sample settings, which I personally am always a fan of, because it gives me an idea of what to expect out of each control and the overall parameters that they cover. I started with the "transparent" setting, which was exactly like it said it was. I could click the pedal on and off and virtually no difference, which was cool. So, next I went through each "preset" so that I could hear what Mad Professor intended the pedal for. After about 30 minutes of that, I decided to just use my ears and find the tones that worked best for me. The controls are Level = output level of the pedal, Sensitivity= overall gain/drive for the pedal, Contour= output tone control, and Accent= pick attack and dynamics. After another 30-45 mins of playing, I can tell that this pedal may begin as transparent, but definitely adds its own flavor, especially once you turn up the Accent and Sensitivity controls. I also noticed that it is actually a very dark sounding pedal that can absolutely get in the range of fuzz territory. I personally liked the tone with the Sensitivity backed off a bit to around 11 o'clock and the Accent control around 1-2 o'clock, with the Contour knob at about the same and Level set just a bit above unity settings. At times, I found it hard to dial out some of the very bass-heavy overtones, especially with humbuckers and p90s. However, with a Strat, it was hard to stop playing it. The overtones worked in my favor making each note have an almost fuzz quality without taking over and sounding like mush. It also seems to like the strat bridge pickup the most. As far as how Dumble-like this pedal is, I can not say first hand, since I have never had the chance to play one of these legendary amps or even a clone. I can only go off of recordings of guitarists that have used them and YouTube videos. I have also never played any other D-inspired pedals, so I don't have anything to compare it to in that regard. From what I have heard of other pedals and the actual amps, this pedal may fall short in delivering the note definition and sustain that D-amps are best known for. The Simble also seems to distort more than what I would call the "Dumble-sound". This of course is an analogue pedal trying to recreate the tone of an all tube amp that utilized cascading gain stages, which is tough to do no matter how you look at it. Not to mention the obvious witch craft used by Alexander when creating his amps. Overall, I think the Simble is truly a quality overdrive and has its uses and place on my pedalboard. I have yet to try extensive trials with stacking it with my other OD pedals, but that will most likely come this week. I hope this review was helpful. I encourage everyone to try one yourself. Who knows, you may have a totally different experience than me. After all, nothing is more subjective than guitar tone.
