The Genzler pedals are great. I use one (4 On The Floor) as an “always on”, together with a Genzler Re-Q.
I have found that this combination can cope with almost any eq and drive challenges in the bands that I play in.
The music styles that I play don’t call for extreme drive requirements, but Genzler has that covered as well (Crash Box 4, I believe).
I tend to hoard stuff on the premise that “it’ll come in useful someday”.
So I have amps in Class A/B, Class D, power-amps and separate pre’s.
My back tells me that a small pedal-board, IEMs and DI is the way to go for me………….but I do get nostalgic for trouser-flapping “heft”.
I gave them a go……..and with a similar reaction as @meterman was impressed. Price/quality is OK.
I put them on a “beater” instrument just for curiosity and they’re still on there and are holding up. Tension is fine.
Another suggestion for the OP if in the market for another bass………….is a NS Design Radius bass. By design, it is more ergonomic than flat-backed instruments. Need to like headless basses though.
Didn’t Fender themselves dabble with this (S1 switch) in order to allow Jazz players to run the pups in series and attempt a more Precision-like sound? Seem to recall it was in some mid 00’s instruments IIRC.
I have one as a back-up in case of problems with my wireless kit. It does not have a limiter though, so I always worry about noise spikes (feedback or dropped microphones) with IEM’s and serious ear damage as a result. The Rolls PM351 is otherwise a great piece of kit though.
