Custom Moog Guitar Amp

Post by perswhite » Sun Mar 24, 2024 12:31 pm

Good day, everyone. Excuse me, but I couldn't find an answer anywhere, therefore I apologize if this is my first post on a new issue.

Whatever the case may be, my Sub Phatty is approx. 5 years old. Because I am a total amateur, please take my ignorance for granted. When I used to play my Sub Phatty, I usually listened with headphones or a digital connection, but now that I'm attempting to put together a proper music setup, I'd like to acquire something finer. My question is, would there be any issues when using a guitar amplifier to play it? The valvestate 2000 is a Marshall product. Without damaging the synth or amp, I simply want to be able to hear myself quite well without headphones, so I'm not really concerned about sonic quality.

For some reason, this makes me nervous. I remember asking the salesperson at a local music store about a completely unrelated recording setup, and he said something along the lines of, "Oh, good you didn't do that because it probably would've fried the amp and/or your computer."

I could use some advise. Much obliged.

According to the owners manual of the sub phatty the ins and outs on the back side are on line level. Which is just standard. A guitar output signal is just 10 to 60 percent of a line level, afaik. So a guitar amp should amplify more than the factors of line level.

Perhaps this is the point the warning of the salesperson refers to. A line level signal of a sub phatty might be too strong for a guitar amp, might be his concern.

If I am right, the picture in the sub phatty owners manual is misleading. There a guitar is plugged directly into a sub phatty, what should result in an input signal which is much too weak. In my opinion a preamp is needed for that, like for a mic.

But this is all theory. What you can do is (fully on your risk) to plug in your guitar amp into the phatty and level both down / to zero: The output volume of the phatty and the amplifying volume of the guitar amp. Then level both up very slowly and with extreme care to avoid unwanted distortions / death of your speakers / death of your ears / earth quake effects on your studio etc. blah blah.

From the technical descriptions point of view it should work that way.
