I got this circuit back in August for a project. Tried it in a bass for about a week, then went with an Active set up. This is a very articulate set up. Excellent breath around the mid-range area. I'd really love to have it on a Fretless bass... or, crank up the tone control and get that Pino Palladino, Paul Young era, "Tear Your Playhouse Down", kinda tone! Tone control rolls off really well. I liked it better with my DiMarzio Ultra Jazz Bass pickups vs the DiMarzio Area J pickups. Then again, I like the Ultra pickups better than the Area set Your PayPal Payment gets it shipped to your Lower 48th US state via USPS with tracking.
