Lehle Mono Volume S pédale de volume

Really robust professional volume pedal. Requires 9v 150ma power from a power supply rather than battery. Works to buffer the impedance - so great at the start of a pedal fx signal chain. Has flange mountings so can be attached with screws/bolts to a pedal board. Can be easily configured to boost the level. Has an additional direct unattenuated output for eg a tuning pedal. Pedal position remains where it was left - this is adjustable so presumably if it starts to flop can be tightened again. Not cheap, but pedals get a lot of use gigging , and hopefully this one won’t let me down on stage
