I would think that he meant to run each amp to each speaker.

Yes, but how do you handle the input from the bass?

 

[Stealth57]

I’ll have to look at the back of the amps.

If one of them has a separate line out, like to go to a recording console or something?, you might be able make it work; it should let you send signal to the second amp without bypassing the power amp of the first.

Question on mixing cabs. My Sunn 215m is 4 ohms. If I get the Trace Elliot, it is 8 ohms. If I run both into the Sunn head (200w @4 ohms) will that cause any issues?

What would happen if you ran the sunn head at 4 ohms into the sunn 215 cab and used your MM head for the trace cab at 8 ohms. A simple A/B box coming from your bass would split the feed into the input of each head. You’d obviously need to do some tinkering to get the two cabs at similar volumes, but it would allow you to run effects through one amp/cab stack and keep the other one clean.

I wonder if this is neck through or set neck?

Looks neck through to me, I don’t see any set neck heel.

If the first amp has two inputs in the same channel you can run the other input to the input on the other amp. Some amps have preamp out and power amp in, many Ampegs have that feature but if not for example with Fender amps back in the day you'd plug into one input take a cord plug it into the other input of th same channel and plug it into another amp. You can do that with two channel amps too to get more variation. Never run a speaker output into an amp input, boom!

Maybe my mixer would work for that. It’s 8 channel.

Does either your Sunn or your Musicman have a high and low impedance input on the same channel? What model Sunn do you own?

Might, but isn’t that usually 8 Channels in and one output? You’ll need one in and two output. An A/B box, technically it’s called an ABY box (the Y allows output to both A and B simultaneously) is pretty inexpensive. This one is about the most expensive one you’ll find, most are under $50.

That's an incredibly smooth neck joint for set-neck. I was gonna guess neck-through.

Looks neck through to me, I don’t see any set neck heel.

My Orville and Jackson, both are set neck......

How's it done? Greco shows us the way.........

Concert Bass circa 1976

Sunn inputs labeled normal and brite

MM has 4 inputs. 2 normal and 2 bass.

You could jumper the inputs of either one to the other one. For ex. plug your bass into whichever input you like better on the Sunn and run the unused input to whichever one you like on the MM. You'll have to set each one the way you want it. I assume your heads have grounded plugs, three prong?

Just need to make a nut and string it up. Going to try a set of broken in RS66S first

Looks reeeaaally good!

Second time this week!

....it might be getting a "new" addition tomorrow.....

Yes, I'm well aware of that.

Have my attention. Waiting.... waiting.... waiting.....

Yes, grounded. Never knew you could go input to input.

Wonder what the pickups are like? They seem to be in the original/vintage positions.

That's beautiful. I wonder why Gibson can't make it that smooth with the NRs.

 

[Chucky Stiletti]

Ok, how do you chain amps?

input to input to input and so on…go into the MM first…..you can also slave the power amp on the Sunn from the “Send” of the effect loop on the MM…careful, playing with these configurations often ends up with smoke…

 

[Chucky Stiletti]

Yes, grounded. Never knew you could go input to input.

you can’t do it always….some Fender amps don’t like it…

I've usually just done it on two channel amps, jump one channel into the other.
