Is the VM ok handling a mismatched load?
Dave, isn't your TL 8 ohm?
HEy Dave ( ya both of you)...I know this whole thread is confusing so let me explain...
I have this pretty nice extension cabinet...10" lil Buddy and a 12" Weber Both 50 watts both 8 Ohms.
The cabinet was wired in parallel when I first tried it on the VM... ( 4 Ohm load)
Amp sounded fine BUT because the extension cabinet is open back, I thought why not try it in series ( 16 Ohms)...
I know all this stuff is very subjective but I will tell you that I think the 16 Ohms setup was a much better match for overall tone.
Bottom line, the VM wants an 8 ohm load with a 4 Ohm min.
I hope this clears things up a bit.
