RowinAnalog Phaser Guitar Pedal with Vintage and Modern Modes Classic Sound 70's for Electric Guitar Bass True Bypass LEF-313

I previously bought a similar one on Temu and after a handful of times using it, it just stopped working. This one feels better and works well. It powers between 4 and 6 pedals on my board at the same time with no problems. I don't expect it to last a lifetime, I don't know if it is truly isolated, I haven't had any issues with unwanted buzz and noise, and for use at home it works, and works well.

I purchased this to use with my Behringer TD-3 Bassline synthesiser and I'm so glad I did as it's turned it into an Acid monster!It absolutely transforms the sound and is so much better than the on-board distortion which sounds rather tame and polite in comparison.As others have mentioned, as you move the sustain past the midway mark it does introduce background noise, but this really isn't noticeable when running a fast acidic baseline through it.All in all, it sounds great, is built well and at a great price too!

This nano size guitar stomp box is real value for money. It's name - 'Dumbler' - implies that it mimics the sound of the Howard Dumble boutique guitar amplifiers, as used by Stevie Ray Vaughan and Carlos Santana. Well, as Dumble is now deceased, and he made very few amplifiers in his lifetime, those amplifiers - if you can find one - sell for tens of thousands of dollars. It's a tall order, therefore, to ask a humble, budget-priced bit of kit to approximate that sound. How would I know what it sounded like, anyway? A Fender Twin or a Vox AC30 or a Marshall - I know roughly how they sound. As a tone boost for lead guitar work, though, it really is excellent. I have a Hughes & Kettner guitar combo, and I simply put the bass / mid / treble controls all at '12 O'clock', plugged the Dumbler pedal in (bear in mind it runs off 9V mains power only - no battery) and started experimenting with it. Initially, I put the volume, tone and gain knobs on the Dumbler at '12 O'clock also. I played a Tokai 'Love Rock' Les Paul copy with humbucker pick-ups, and on the bridge pick-up the Dumbler adds a pleasing cutting edge, the pick‐up is quite fat-sounding, but the pedal adds intensity and bite. Dialing up the 'voice' adds a little dirt into the sound, but whacking up the volume pot with gain at the middle really adds a bit of rasp that is full and dynamic.I am no electric guitar virtuoso, but I like a good guitar sound - I haven't tried it with my Telecaster, Stratocaster, or my P90 pick-upped Peerless semi-acoustic, but I am greatly looking forward to putting the Dumbler through its paces! In the meantime, so far so very good, and at this price you simply cannot afford NOT to check the Dumbler out!

Very nice. Just the kind of distortion pedal I needed. Not suited to every genre but for me it was just the ticket. Mine works flawlessly.

No software available for Mac, and I couldn’t get the Windows version to work either. So it’s not possible to export loops you want to keep, or to import backing tracks/loops. No wonder it’s so cheap.Aside from this major mis-selling by Rowin, the pedal is also terrible as a standalone looper. The reverse and speed modes doesn’t work at all on the one I received.Knew it was too good to be true at the price. Returned 10 minutes after unpacking it.

Very Good great quality

Needed a spare, didn't want to spend a fortune. Good price and arrived quickly. Saves space on the board and does the job perfectly well. Just what I needed.

Bought this for home use but found that it needs mains power NOT a 9v battery, should have read the item description! So haven’t been able to use it yet, online reviews say that it’s good but none mention the power issue so beware.
