Peavey Forum

So I stumbled upon a Musician 400 Series head and matching 212 cab for $200 (reminded me of my teenage years!). Took the head in to our local music shop and had it cleaned thoroughly. Works great! A couple questions though. My model has the additional parallel and series inputs. Can someone explain their purpose and function? Also I cannot find the foot switch (remote switch) anywhere. I think it's a 7 pin switch with Effects Reverb and Tremolo buttons (I have a photo of it but can't figure out how to upload it here).

Thanks for the help but that manual is not for my Musician 400 Series, it is for the Mark III which is significantly different. There is a manual for the Musician but it is without the parallel and series inputs.

The controls ought to be self-explanatory. If you want to know how the series and parallel jacks work, read the input jack descriptions in this manual for Classic. They work the same there.

How about a complete list of the buttons on the footswitch? Is it a 5-button?

Look at the top of this section, Roger has a sticky post of tech tips. The very last one is a collection of footswitch wirings. Perhaps the Musician-B one matches yours?

Nice... thanks (for all the replies) gang. I'm new to this forum. I was able to find and save a copy of the Footswitch wiring. And thanks for the link to the Classic manual...I think I understand the Parallel and Series inputs now... what's really cool is that the Classic in that manual was my first big amp purchase back in the mid to late 70's! I remember eventually replacing the speakers with EV Force Speakers at the time...not to long ago I stumbled upon EV Force Speakers on Ebay and e-mailed the person in New York selling them. He had removed them from a Peavey Classic...very possible it was my old amp! Great memories.

I found a picture of someones Peavey Musician (and 412 cab) identical to mine with the footswitch. I saved the photo of the footswitch. It is a 3 button switch. Buttons include Effects Reverb and Tremolo

My first post, new here today.
Anybody have a wiring schematic for a pre Mark III Series 400 Musician foot-switch?
It's a 5-button. Selector, Combiner, Reverb, Tremolo & Effects
Here's the pics . . .

Thanks for your post. Not sure why your referring to your musician as a Mark III. It's simply a Musician 400 Series. I think there's other threads here addressing your question about schematics. I have the complete setup; head, matching 412 cab and exact same foot switch. I think the more important questions here are: is it the correct foot switch for this head and if so, which input should I be plugged into? any help would be appreciated...oh, by the way Cereal_Spiller, no need to email me privately. Do to spammers and phishing, I rarely reply. Plenty of help to be had right here and the forum can notify when the thread has a new post.

Contact customer service at the factory, and they will send you any schematic you want.

I referred to the "pre" Musician 400 MK III.
Anyway Peavey does not have the schematic for this particular pedal.
I will create the schematic and post. Check out this rare sight.
I now have two with pedals . . .

You need many more speakers

I picked up an old worn 400 head & it works relatively well after i pulled it apart & cleaned the pots & built a new head cabnet. I was surprised that there was no internal metal chassis. I play bass in a classic C&W band and play bass through that head and into an old Peavey 1820 cab i just picked up last night. I spent all day today pulling 'that' cabnet apart, removing the speakers, grill, hardware, etc. & scrubbing about 20 years worth of cigarette smoke & whatever else it had aquired as a 2nd 'skin' (yuk) off it & reassembling it.
The 400 makes a pretty damn good bass head!

Part of me wants to break the head down to something smaller by converting it from a pcb based circuit to point to point wiring & possibly replacing all the somewhat worn & scratchy pots & as many of the components as possible. The thing is damn heavy! I am going to install a power jack in the rear panel to have a removeable power cord (and a longer power cord in the process!) like 'newer' amps have just for the convenience.

Peaveys gear was modular, in the sense they had different back panels, which were the power sections, and different front panels which made it a guitar, bass or mixer amp

<slaps self on forehead>
That makes too much sense!

The Mark III Musician was a later model, it had the five input jacks in a group on the left. The preamp was based on ICs.

The Musician - plain old Musician - came first. I have drawings for the 200, 300, and 400 series of Musician. If I have them, Peavey has them.

The 200 was basic, hi/lo pair input jacks. Fuzz, trem. Schematic calls for a "to reverb drive" but includes no reverb circuitry. I don;t recall if the amp had reverb or not.

The 300 series was a little fancier, same hi/lo input jacks. It shows a reverb as well as the fuzz and trem. Also has the Spectrum selector switch.

The 400 series is like a grown up 300. Same hi/lo inputs, plus reverb/trem/fuzz

But there is also a Musician B-series, and I believe that is what Cereal has. Got the hi/lo jacks for each channel PLUS the series and parallel jacks. Fuzz/trem/reverb too. AND it has the five-button stomp switch.

Ask Peavey for the "Musician B-series" schematic. I don't have mine scanned. It covers the preamp, ie. the front panel. You will have to determine which power amp is used, ie. the rear panel.
