Overall Impression

The Boss FV-50L is a passive low-impedance volume pedal for use between a guitar and effects or amp. One user has used it since the '90s between their pedalboard and amp, calling it sturdy with no complaints. Another user reports signal loss even with the pedal fully open when used after distortion pedals. They measured around 18 ohms of resistance at volume 10. This raises the question of whether the FV50H suits placement after other pedals. A separate user notices treble loss when the pedal is set to its lowest position. They are considering a treble bleed modification to the potentiometer. Someone also asked whether it could work as an expression pedal for a Zoom GFX1. Overall, feedback suggests solid build quality but some impedance-related tonal tradeoffs.

One user has run this pedal between their pedalboard and amp since the '90s and reports it still works as it should with no complaints. This suggests the FV-50L can hold up to decades of regular use.

@NevilleDeNetto

I've been using the FV-50L in between my pedal board and amp since the '90s. Sturdy and works as it should. No complaints here :)

warningSignal Loss After Distortion

1 mentions

Frequently criticized

A user placing the FV-50L after distortion pedals notices signal loss even with the pedal fully open, measuring around 18 ohms of resistance at volume 10. This has them questioning whether the higher-impedance FV50H would be more appropriate for that placement.

@brunobrugnolo

I use my FV50L after distortions, and I feel a signal loss even with the pedal fully open. I measured the resistance and got something around 18 ohms with the pedal at volume 10. Is that correct? Should I replace it with an FV50H to be able to use it after pedals? From what I understood the L is for guitar to go straight into it and the H is for placing it after pedals, am I right?

1 mentions

Generally negative

Another user reports losing treble when the pedal is set to its lowest position, prompting them to consider a treble bleed modification on the potentiometer. This points to a tonal tradeoff at low volume settings.

@new1old

I’m losing treble when I have the pedal set to lowest position. If I wanted to add a treble bleed to the potentiometer, would it be to the 250k pot or the 500k minimum pot?
