Hey-
Not 100% sure how this is supposed to work, so I may or may not have a problem with the amp. Here goes:
When I step on the solo boost feature, the amp gets way loud. When I step on the footswitch to cancel the solo boost feature, and turn the solo knob, the volume still changes. Shouldn't turning off the solo volume mean that knob shouldn't effect the normal volume?
Is there a solo boost volume that is the same volume as the standard channel - in other words, if I step on the solo boost, I should get no increase in volume. Know what I mean?
Andy

I actually called Splawn, and got the answer - The solo boost knob effects both the normal volume, and the solo boost volume. Josh at Splawn also said to always have the solo boost volume at around 9:00 or higher - this helps fatten the normal volume tone at lower volumes.
Who knew!?

Actually, it turns out that I have some kind of problem with the amp. When I move the solo boost to anywhere but Zero, the volume is way too loud, and the channel switching doesn't seem to work. When I pull the footswitch out, I get back to the gain channel, at the normal volume.
Can someone check their modded Marshall, and see if it does the same thing? Otherwise, I plan on sending it back to Splawn to have them check it out and make sure all is well.

Hmmmmmmmm, ok ,lets start with the channel switching. If the footswitch is intermittent, its probably a simple wiring problem in the switch itself. If your handy with an iron, you can do that yourself, check for shorts. The solo boost on my early 06 QR works exactly as your stating. Anything slightly above '0' is a HUGE increase in volume! I figure thats the way its designed and you have to be careful when using this feature.

I think there may be a problem. The ONLY thing I noticed is that it's really touchy (level-wise) at bedroom levels...but is
much more linear at gig volume.
BTW...I know this is unlikely but...
Don't plug the FS or guitar input into the WRONG jack.
Iv'e done this before...it didn't blow anything up but...

Right -0
I have a Splawn modded Plexi and a 1st generation Quick Rod.
It takes a little more tweaking for the solo boost function. It also sounds great to leave the solo boost on all the time* and just use a boost(graphic EQ) for solos.
*as if it didn't have enough berls already! ;D
And yes the master volume,preamp volume, and solo volume feed off of each other.Different settings produce varying results.To my ears anyway.
These amps have way different characteristics depending on what volume you play them.They are not (much) different than older Marshalls in that respect. More volume= growing a pair......the louder the bigger the set.......
Experiment and Discover....................................

I'm confused. When I pull the footswitch out of the jack, my amp goes to the lead channel, and the volume is linear and works fine at lower volumes. Solo boost does nothing with footswitch disconnected. When I plug in the footswitch, the volume shoots up to concert level. I assume it's the solo boost channel, so I step on solo boost on the footswitch, and it stays just as loud, only buzzes (like an old Plexi on 10 would sound)??

Thats not right. Have you checked the wiring on the switch yet? If not, Id strongly suggest that. If you dont feel comfortable, it should be easy to find someone who can help you out locally. It would be a bummer to send your amp off to Scott if its something really simple.

Is checking the wiring on the footswitch pretty straight forward? If everything is connected properly, the footswitch is ok? I'd much rather it be a footswitch faulty wire than have to mail the amp to Splawn and wait a month or two to get it back!
Also, will ANY two-button footswitch work, or is the Splawn version special?
Thanks.

I'm no electronics genius Andy, but yeah, you should be able to at least check the connections, and wiggle things around to check for shorts. Check both ends and see if you come up with anything. Ive never been into my switch, but Ive had some intermittent problems that I need to check also, Ill take a look this weekend and Ill report back if anything stands out that you should check....

The FS function is pretty simple actually. The tip to ground activates one function and the ring to ground activates
the other.

I actually fixed the problem. I sprayed the footswitch buttons with contact cleaner, stepped on them a dozen times or so, and plugged it back into the amp. Problem solved. Strange, I guess the footswitch buttons weren't making good contact, leaving the amp half in or half out of the channel, etc.
I think I am good to go now.
