The Valeton FP-10 is a compact FET preamp pedal from Valeton, built around a 100% analog signal path. A FET (field-effect transistor) preamp uses transistor stages to add gain and shape tone, and the FP-10 adds up to 26dB of it, with bass and treble EQ and a low cut switch for trimming low end. It is a simple, small unit aimed at pushing an amp or cleaning up a signal chain. Valeton lists it as discontinued on its product page1.
The controls
The FP-10 keeps its front panel to three controls1:
| Control | What it does |
|---|---|
| BASS | Controls the low EQ level1 |
| TREBLE | Controls the high EQ level1 |
| FLAT/LOW CUT switch | For cutting low frequency when switched to low cut1 |
The low cut filter is fixed at 200Hz with a slope of -6dB per octave, so switching it in removes a set slice of low end rather than a variable one1. A volume control sets the output level, which Valeton describes as controlling the output volume (gain)1.
The FP-10 is buffer bypass, not true bypass. When off, the signal runs through the pedal's buffer1.
Power and practical details
The FP-10 runs on 9V DC center negative power and draws just 5mA, so it is an easy fit on any pedalboard supply1. The casing is zinc-alloy die cast, which Valeton says is to withstand wear and tear1. At 94mm deep, 48mm wide and 39mm tall, and 280g, it takes up little room between other pedals1.
Manual
Valeton makes the FP-10 user manual available as a download on the product page1.

Questions
Is the Valeton FP-10 fully analog?
Yes. Valeton describes the FP-10 as having a 100% analog signal path. It is a FET transistor based preamp, meaning the gain and tone shaping are done with analog circuitry rather than digital modeling, and there is no digital conversion in the audio path.
Is the FP-10 true bypass?
No. Valeton specifies the FP-10 as buffer bypass rather than true bypass. When the pedal is off, your signal passes through its buffer. That can help keep the signal strong on longer cable runs, though players who prefer a fully mechanical bypass path should know the difference.
What polarity does the FP-10 power supply need?
The FP-10 runs on 9V DC center negative power, the same polarity used by most standard pedal power supplies. It draws only 5mA, so it sits comfortably on a daisy chain or isolated supply alongside other pedals.
How much gain does the FP-10 add?
Valeton lists the FP-10's maximum gain at 26dB. That is enough to push an amp or a power section harder from a clean platform, or to bring a low-output pickup up to level.
What does the low cut switch do on the FP-10?
The FLAT/LOW CUT switch engages a low cut filter set at 200Hz with a slope of -6dB per octave. Switched to low cut, it trims low frequency content, which can tighten up the sound when running into an amp or a full-range setup.
Can I download the FP-10 manual?
Yes. Valeton makes the FP-10 user manual available for download on the product page on its website.
