1590B · 2 knobs
From the vendor
Our take on the zVex Trem Seeker. The oringal is 9mm pots and squeezed into a 1590B – we’ve made this more DIY friendly and sits in a 1590BB.
You can get some really weird sounds out of this and there’s some mods included to make it even more fun.
Controls
• Speed
• Steps 4/6/8 (Toggle switch on/off/on)
• Stop (on/on – stops the effect)
• Step 1
• Step 2
• Step 3
• Step 4
• Step 5
• Step 6
• Step 7
• Step 8
Note: There’s a lot of pots and LED’s on this…measure twice and all that…
