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…
