Please help me identify footswitch sockets in my Mark IIB

[Tommy]

Hello,

I have mark IIB witch eq and reverb.
The manual says that there is stereo socket located beneath the chassis for the optional Dual Footswitch which can be used to activate graphic eq and reverb.
Yeah!

but...
There are three sockets beneath the chassis in my boogie! :lol: Two jacks ( numbers 1,2 in the pictures) and one cinch (number 3 in the pictures). Can you tell me which one is for eq and reverb footswitch? Is this possible that there is also socket for gain boost switching?

It's number 2, I use mine all the time

I do not have jack number 3 though. So I dunno what that's for...

#1 is for slaving out to another amp at least on mine it is.

I've checked this.
Number 2 is for eq and gain boost :twisted: (two button footswitch with stereo jack plug) - huh, so it's four footswitchable channel amp: clean, clean+gain boost, lead, lead+gain boost. :wink:
Number 3 is for reverb (simple one button footswitch with cinch plug).

Thanks for help. :mrgreen:
