I heard he is using Marshall DSL's for BCC

I am using 50watt HRM and a Stray Cat 30 as my dual amp setup and switching / combining them with a Dunlop George Lynch Tripler.

My HRM goes into a EVM12L in a homemade Theile Cab and the Stray Cat into a Marshall 4x12 with WGS ET-65's.

It has worked out really well for the sound I want to get as I prefer the HRM for cleans and the Stray Cat for lead.

The only drawback of running a dual rig is finding room in the car to put all the gear

ok, whew.  if i understand correctly it's a JSX Satriani model, and if it is the tube closest to the first EL34 it's the PI tube. was it physically broken like cracked, or just burned out?

the 3rd 12AX7 is the PI, or Phase Inverter tube.

the 3rd 12AX7 is the PI, or Phase Inverter tube.

there are 4 12ax7's, 1 sits byself right next to power tubes ( PI I think )
the other 3 are offset behind xfrmr ( 2 are preamp tubes )
the last one I still dont know what it does.
I havent spent much time yet trying to figure it out cause I have this brand new OTS that wants to be played
This coming weekend I will dig into this amp.
Ive never even removed chassis to look inside so it should be fun

Thanks again to all
Pickmaster, love the setup. I should know this from all the other posts of yours ive read but are both OTS original ( no mods ) if not which mods on each?

Doc, I know that one of the extra pots on the front fascia is the OD treble bleed mod, but whats the other one? PAB level?

Thanks

Hi,

long time since my previous posting...

I'm running 2008 OTS 50 and '68 Marshall plexi 50W parallel to vertical Mesa 2x12 metal grille cabinet from early 90's. OTS is feeding the ported thiele part of the cabinet, which has 80W Celestion Century G12 inside. Marshall is feeding the open-back top portion of the cabinet to Mesa C90. Splitter box (guitar signal) is Roger Mayer Crossroads.

Both amps contibute to the sound at the same time. First I dial a good crunchy tone from the Marshall alone with more mids, than bass or treble. Then I fine-tune a good lead sound from the OTS alone.  When I combine the sounds, I'm adjusting the Marshall to slightly dominate the rhythm sound for crunchier rock tones. Here OTS clean channel provides most of the bottom end and the high end "air". For solos, I kick in the lead channel from OTS.

My experience is that if I try to make both amps sound great on their own, the comibined tone is not as satisfying as when I "layer" the sound of the two amps, with different tonality.

There are couple of things that make this setup less optimal:
1) switching guitars between songs takes more time, if pickup outputs vary a lot
2) requires two channels from the PA

Despite of the shortcomings, the resulting sound is extremely addictive. The setup is also fairly portable, with two heads and one small-ish cab. Since we don't gig so often, I haven't made any changes to my setup for a long time (therefore, no visits to this forum either...) Now I'm looking for an alternative for the C90 though.
