This preamp is great!

The options for tone are amazing, the ability to use a Tone Control and also use the High control to mix up the sound and get a bright tone without harsh highs is amazing.
Once you switch to passive mode, you have volume/volume and tone to use, so you can mix up the sound just like in a Jazz bass.
I can recommend this preamp, is very musical, you can get an excellent tone and great combinations.
