Hi out there! I am the happy owner of a Maz 38 SR top and lately I wondered: What if my fellow-guitarist's amp - in case a brandnew Peavey Classic 30 112 lets him down again (this week it went completely dead with only a little light in the preamp tubes and nothing in the 4 EL 84 tubes) could I then - just to "rescue the show" - plug his guitar in the other channel of my Dr Z top??

Don't think so, but I could be wrong.

Not an answer to your question, but my PV Classic 30 did the same thing. Some of the jumper wires connecting the 3 PCBs needed replacement.

I don't konw either? I've done that with my old Deluxe, one in the normal channel one in the Vibrato channel... Not sure on the Sr though? I may try that tonight to see if it works? My 5 yr old is dying to play with me,or make noise with me.

Well I am sure, it is not a good idea generally, but I wonder, if it could damage anything? I have downloaded the (short) Maz 18/38 manual, that says nothing about it neither warn against it. Of course you normally just use your own amp, but with two "inputs", it is obvious, that it could happen or someone would be tempted to try.

You guys are kidding, right??
Of course you can plug 2 instruments into one amp. There will be no damage. I can't even imagine what spooky principals or folklore could even dream that concept up.
Your amp doesn't have 2 channels, so the settings will affect both guitars--this is your limitation.
Back in the day, entire bands would plug into one Fender Bandmaster or Vox AC30.
It might be a good idea to get a book, or even use the "google" to read up on how amplifiers work, and how they are wired. It could be useful.

It would work but not too well. A little mixer would help otherwise one would be in the low input and one in the high causing a volume difference.

My buddy and me used to both plug our guitars into my Fender Princeton Reverb, but it seems as if ever since Ghostbusters came out on video, guitar players nationwide have been afraid of crossing streams.

Assuming the Zs inputs are wired like a Fender, Marshall, or just about every other amp (except older Mesa Boogies), then both inputs will give the same level to the preamp when they are plugged in at the same time. The padding resistor ends up being bypassed. P.

The padding resistor ends up being bypassed. P. "assuming" Last time I discussed this with a reputable Z dealer I was informed Z's are not wired like a Fender/Marshall - so you will have 1 HI, 1 LO. I had initially assumed the padding resistor would be bypassed as well being from the Fender camp but decided to ask to clarify. ----- FYI, there are a lot of hobby/novice/non-gear geek folks who come to this forum to ask questions because they know they will receive positive/supportive asssistance from knowledgable folks w/out the side comments typically found on TGP and other music oriented forums. While the input is greatly appreciated, the tone isn't: "You guys are kidding, right??" "I can't even imagine what spooky principals or folklore could even dream that concept up." "That's not right either. Assuming..." Just a head's up - this forum, more so than others, has a positive character and culture - it's very cool/tolerant/open-minded and self policing to help keep it that way. It's all good, just keep it positive/helpful, and have fun.

OK, I should not have assumed anything about the wiring. I will open an amp up tonight and check it out. I may be right, I may be wrong. Sorry about that.
Now as far as the tone--I guess I get a little upset, not at the question, but at the fact that people think it's OK to post answers when they don't actually know the answer. I think this is more of a problem for the novice/hobbyist than a little sarcasm could ever be.
But then again, I'll admit perhaps I'm wrong about that too.

No need to get upset about anything said, it's not life and death on this subject. A correction is always appreciated. I was just assuming the resistor would still be in circuit. So I should've tried it out myself before I commented. The last time I did try to plug two instruments in the same channel on an amp the volume control on one guitar turned down both guitars. I don't remember what amp or anything else about that situation, just remember it sucked!

Not sure about Z's but have done this in my High School days with not great results. From what I remember we got a drop in volume and tone, to the point of me thinking it wasn't worth it. But that was a long time ago... So whats left of my memory may be lying to me.

Standard Fender/Marshall amps will drop to the low input level on both inputs when two instruments are plugged into the amp at the same time in the same channel. My 70's Pro Reverb, Twin, and Deluxe did that. Sounded a bit anemic/thin when run that way. Never tried it with something like a Les Paul (higher output pups)...usually played single-coil equipped guitars.

I remember reading something once or twice about gaining wisdom by consulting a variety of sources; variety is our middle name.

One alternative suggestion is to bring a DI and plug from the guitar to pedalboard to DI to PA and just let him come out the front... or bettah yet, if you have a PA with monitors, just put that guitar player in an aux channel and a monitor with nothing else on that monitor mix and place that monitor behind him like an amp. It will work in a pinch.

This also has to do with both imputs being buffered (or not) I believe.
Doc has posted here that you 'can' run through an A/B box to 'channel' change on a MAZ, "It will pop like hell" I recall him phrasing it. So I'll take that you 'can' run two guitars in a pinch...but I would drop a PM to Brent and ask the source.
Now, my Greer does not have buffered imputs and if you plug into both imputs OR toggle between them you will hear a strange noise, see a puff of smoke, then hear nothing at all...except your check book screaming.
A DI box,as Paul mentioned, is a nice back up plan.
I tote the ever handy Orange Tiny Terror head for these occasions should the need pop up.
