I have a couple, but I never really use them. Actually, one of our guitarists is permanently using two of them on his pedalboard
[*:28ejonl8]Rodenberg GAS828, a twin-pedal guitar overdrive that works well for bass too;
[*:28ejonl8]Fulltone Bassdrive (the second version, without mosfet mode but with 3-way switch). Great classic sounding overdrive, but even better for guitar;
[*:28ejonl8]EBS MicroBass II preamp & DI with built-in drive channel. My main rig has been an EBS HD350 with an EBS Proline 4x10 for the last couple of years, and I got the MicroBass to get as close to that tone as possible without having to lug around my halfstack to rehearsals. My band now has its own rehearsal space, so I can permanently leave my amp there and I'm not using the MicroBass II anymore, but it's still a great tool so I like to hang on to it;
[*:28ejonl8]Boss SYB-3 synth pedal, capable of crazy synth and envelope filter sounds. I got it for mimicing some Muse sounds at home. Traded in a Hartke VXL Bass Attack for it;
[*:28ejonl8]EBS Red Twister, an old chorus pedal by EBS. Great sounding pedal, I got it NOS at a great price. Very similar to their current UniChorus;
[*:28ejonl8]EBS MultiComp, I like how musical and subtle it can sound;
[*:28ejonl8]EBS OctaBass, very clean suboctaver with great tracking. Very tight. A bit subtle though, because it's so clean-sounding;
[*:28ejonl8]EBS BassIQ envelope filter. A very modern sounding envelope filter capable of downright crazy filter sounds. I love it. But never use it, I have no use for it in my current band. I mostly bought it to have fun with at home;
[*:28ejonl8]Maxon AF-9 envelope filter. Classic, very warm-sounding envelope filter with many tonal options. I like it better than the EBS;
[*:28ejonl8]Dunlop Crybaby 535Q wah, I was given this by a friend. It's an old 18V model without status LED. I had it modified with an on-off status LED. Really cool wah with a powerful volume boost and a rotary switch to select the frequency range. This is now on the pedalboard of one of our guitarists;
[*:28ejonl8]Ernie Ball VP jr 250k volume pedal. I originally got the 25k version for the FX loop of my guitar amp, but traded it with the 250k version of one of our guitarists, who now uses it as an expression pedal for his FX rack. The other guitarist now uses my 250k pedal.
I also have a Line6 Bass POD xt at home, but that has been sitting in its box for the last 2 years.
I once intended to build a pedalboard to actually put all of this to use (I even have an MXR DC Brick power supply), but in the end I'm more of a plug and play type of guy. Give me a good bass and a good amp, and I'm a happy camper!
I don't really use any pedals at home anymore because I don't have an amp at home. I always plug straight into my mixer and play through my active monitor speakers (KRK V4 Series II).
