Mesa Boogie Mark V 35 FOOTSWITCH Schematic & Pinout

[jimkeaney]

Today I asked Mesa Boogie for the pinout on the Mark V 35 Footswitch (5-pin Din jack) and they sent the whole footswitch schematic over immediately. What a great company I figured I'd add it here for future reference.

I just successfully built a 5-pin Din Male to 2x TS(Female) project box (velcro'd it inside the rear compartment of the amp), so now I can use my 2 button footswitch to control Channel and SOLO without using the large 4-button stock foot switch that comes with the Mark V 35. As shown in the first page, I used pin 2 for Channel +, pin 3 for Solo + (ps it engages SOLO on both channels) and Din Shield "SH" (sleeve). The reason I used 2x TS instead of a TRS 1/4", is because I also using this foot switch with my Mark V 90 Head (which has individual 1/4" TS for various channels and solo).

Jim, could you make me one of these? Of course, name your price for the parts, shipping and your time.

Thanks.

This might be an option for you.

I wonder how similar this switching relay is to the V:90?

I've got an intermittent issue with my V:90 where switching to channel 1 from 2 or 3, the channel itself switches but there's no signal unless I switch to another channel and back again. I've ruled out footswitch, because it happens with both DIN and 1/4" solutions. I'm guessing I might have a faulty RY10, RY10A, or RY10B?

No way man, I feel your pain I'm dealing with the same exact intermittent problem except it is when switching to Chan 2 from Chan 1. Less of an issue going from Ch 3 -> Ch 2. In my case the Chan switches, I see the led go on and there is still sound but at a very low vol, it starts cracking and then it takes a sec and kicks in fully. I've eliminated the FS and 1/4" jack controls as well. It was enough of a problem that I couldn't continue with it live and since have been using the Badlander (which I luv). I do miss having the 3 chans and that V clean but it's all good with the BAD.

I have not internally poked around but plan to. I feel it's either a relay or a problem with the Mute circuit. Been reviewing with @bandit2013 but since it works in my studio setting I'm kinda hoping it will get worse so I can find the problem easier.

Oh man that sucks. But also... FINALLY someone else experiencing a similar issue lol. I've been searching and posting threads around the web for like 6 months and havent found anyone else with a similar problem lol. Let me know if you end up getting to the bottom of it...

I've also put the V on gig probation which sucks because I really like it for live use. Just using it at home for now though...

Exactly... when I go to the studio and fire it up I'm like dang. Yes for sure, I think once I get in there and test I'll figure out something. I thought of taking it to Mesa but I didn't want to let it sit for months.

The switching network for the V90 is a bit complex compared to the 2 channel Mark V25/35. Most of the complexity is the configuration circuits used for each of the channel power modes.
