I want to add a volume pedal to my new pedalboard build and don't know whether I need an active or passive one. My board is a mixture of ZOOM G3n (non-pedal version, obvs) and about seven/eight TC Electronic stomp boxes, powered (possibly) by a 1Spot, with daisy chain. Been doing some Googling... The first pedal in my chain is the Polytune 3 with Bonafide Buffer... so I'm guessing a passive pedal is okay? And my guitar is a Tele (what else), so 250-500K for the pedal, right? I'm looking at secondhand Ernie Ball pedals. Is there anything else you can recommend for around $100.00 used.
