This bass you're plugging straight into the amp - is it active? 😜
I had no pedals for years and years, but a project I was involved in for a while needed occasional use of some pretty strange effects. I bought a multi-fx - a Boss GT-6B. The project eventually folded but I kept the pedal. Most of the time it's on a "pass-thru" patch and only used as a tuner and mute between sets. However there are a few songs we do where I use effects, and it's nice to be able to set up a patch without having to add more pedals to a board.
Stranger patches I have set up include a ring modulator/echo for the lawnmower noise at the start of Genesis - I Know What I Like (In Your Wardrobe), and an echo/wah/phase shift I use in Frankenstein by the Edgar Winter Group.
My current favourite is the OctaFuzz patch. It's nice to be able to spice things up a bit, especially in a G-B-D trio
