I bought a Roland 30 Bass Amp from Dolphin which has great on-board modulation effects - the WAH in particular is fantastic at all volumes but I was missing the Overdrive sound for a good Muse impersonation - all I can say is JOB DONE!

Great pedal, provides the top overdrive sound avalible on the market.

Whether it is the subtle growl needed for classic rock or the full blown overdrive for metal.

Sounds great when used with other FX as well. I often use it with flanger, chorus, delay and wah and each sounds exeptionally individual.

I liked and prefered this product for many reasons.

Firstly the design is perfect as with all boss pedals; small, compact and easy to use yet rigid and resistant to damage. The colour stands out perfectly on stage and looks great within a pedal board, the red led is a great help to see if its on or not, but a single pluck of the string would tell you that!

Secondly the sound is outstanding, the five different buttons allow maximum customization but are simple and easy to use. Level, EQ (2 ways), Balance and Gain are all changeble.

The input and output slots are clearly marked to avoid confusion and the pedal can be run using a 9v battery inserted at the base of the pedal or with an external power supply.

Well worth the cost and so simple and easy to use.
