Review: Surprising quality and versatility at this pricepoint - Features I like: - Tone knob is a high pass filter, meaning at full it treble through without boosting, and as you roll it back from full it cuts your treble. Very very useful feature to tame high frequencies of the pedal itself as well as anything you feed it (like a fuzz, say) - Voice knob is a mid-boost with no cut, meaning at off position your mids are not affected, and boosted as your turn knob to full. The "voice" of the mid-freq that gets boosted is very musical, so you can go for no colouration or unique voicing here. More on that next. - With the tone turned up all the way, gain turned down and voice turned down all the way, pedal acts like a pretty transparent boost, except I haven't seen a boost with a high-pass filter as a feature which I think is great. - Sound quality of this pedal is suprisingly good! The breakup of the gain and tone shaping is very musical. No discernable increase to noise floor, pass-through does not colour signal. Parting comment: I haven't played the Vertex Dumble-style pedals that Rhett Shull uses (check him out on YouTube), but to my ear this is a comparable Dumble-style sound at a way way nicer pricepoint with virtually no drawbacks. This is a no brainer purchase - great job iSet.

J J ### ⭐⭐⭐⭐⭐ 値段とか関係なく良い音です *by 旅***人 on 14 July 2025* 他にも様々な種類と価格のODを持っていますが、このDumblerは普通に好みの良い感じの歪みをだしています。簡単に持ち運べるミニ・ペダルボードに乗せて使っています。 ### ⭐⭐⭐⭐⭐ Amazingly rich tones in a nano footprint *by A***K on 2 December 2020* Dumbler pedal: The Dumble tone is a thing of legend and rightly so, Robben Ford comes to mind. Dumble amps are almost out of reach for the average guitar player, but the Iset Dumbler pedal can get you close. This is a well made nano pedal that has 4 knobs: - Volume: Self Explanatory. - Tone: Bright on the left and darker on the right. - Voice: Now this is, in my opinion, what makes this pedal so special! The Dumble tone is known for having pronounced mids and upper mids, the Voice knob on this pedal, is very powerful. I slapped the pedal in front of my practice amp and tried out several variations. At about 2 o clock, it gave me some amazingly rich and resonant upper mids that I had never got out of my practice amp before. Cranking it up adds more brightness without ever being harsh. Full marks to ISet for getting this right. Below noon, you get a fat bassier tone, which is good to balance your tone if you're using a brighter sounding guitar. This knob is pretty powerful, so take your time and try out various positions. - Gain: Self Explanatory, the way I would describe the gain on this pedal is 'sweet sounding'. You can go from a clean boost to a reasonably hot overdrive. The pedal is very quiet when bypassed which is really good. It's very compact (fits on your palm) and won't take much space on your pedal board at all. This pedal is pretty versatile but is particularly great for a fat, rich bluesy tone and other low to mid gain styles. Cranked all the way up, it does some great crunchy rock tones as well. In summary, get this pedal for getting some really cool tones out of your rig. Delay Pedal: The ISet Delay pedal is another amazing piece of equipment for those seeking quality warm analog sounding delays and echos on a budget. The pedal has three knobs - Echo: This is akin to a mix knob, all the way down is your dry guitar and all the way up is where you're letting all of the pedal sound to come through. I found my preferred setting at around 2 o clock. - F. Back: This is the feedback knob to control how many repeats you get, just past 8 o clock was about one repeat. Cranked all the way up is a never ending delay loop, which can be fun to play with. Somewhere around noon is a good 3-4 repeats. - Time: This is the time between the repeats, Leave it at around 10 o clock for a cool slapback delay effect! Crank it up in tandem with the Echo, for a wet, satisfying lead tone. This pedal like the other ISet pedals is very quiet when bypassed which is awesome. The tones are warm and don't sound like digital delays, which is always a plus. The casing seems durable and the on off button is sturdy and satisfying to click. Great job, ISet! ## Frequently Bought Together - ISET Guitar Dumble Overdrive Pedal Classical Blues Mini Single Effect Pedal For Electric Guitar Bass True Bypass - MOSKY Golden Horse Overdrive Effect Pedal Boost Guitar Effect Pedal with True Bypass for Electric Guitar - Amazon Basics 1/4 Inch Guitar Patch Auxiliary Cable, 6 in, 6-Pack, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/342327332-iset-guitar-dumble-overdrive-pedal-classical-blues-mini-single-effect](https://www.desertcart.be/products/342327332-iset-guitar-dumble-overdrive-pedal-classical-blues-mini-single-effect) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-02*
