It’s a relatively easy and very rewarding build. I build two of these at the same time. For the first build I used whatever I had on hand and for the second I used all WIMA capacitors. I would say spend the extra money for the better capacitors the end result is a more crisp and responsive tone. As I don’t dabble much in bass pedals, I decided to do this comparison to see how much it would really affect the tone. The end result either way is excellent but noticeably more quiet, tighter, and more responsive with the WIMA caps. This thing has a massive amount of gain and will offer about a 200% boost over unity. Even when running in flat attack and grunt (both switches centered) there is a exponential boost in mid-bass and treble. I’m not a bassist, my wife is. She was quite happy with the tones when played front end through an Orange CR100BXT. The audio quality of this build is on par with her store-bought Dark Glass Alpha Omega Ultra.
