Warren DeMartini

This source shows that Warren DeMartini used the Soldano SLO 100 100-Watt Tube Guitar Amplifier throughout his career.

In this interview, regarding the recording of “Out Of The Cellar”, Warren states:

Did you really use a Fender Super Champ to record the solo tones on Out of the Cellar?

Yes, a Fender Super Champ, and I disconnected the speaker and plugged it into an EV speaker that was loaded in an Orange cab. I had an orange cab with four 200-watt EV speakers – the thing weighed about a million pounds. We went directly into one of those speakers and mic’d that up.

In this article Warren talks about gear he used on Infestation track “Last Call”:

That was a recorded on my Charvel [Frenchie, not currently offered as a production model]. The amps were a Diezel V4 [VH4] and Soldano SLO 100-watt. We plugged them both in and sort of split the frequency spectrum up: the lows of the Diezel combined with the highs and upper midrange of the Soldano, so you have a really nice slash across the spectrum. I used that [setup] on every song except the rhythm guitar track on “As Good As It Gets.” That was the Diezel only through a Diezel cab. [The Soldano also was run through Diezel 4×12. If the cabs were stock – Warren wasn’t sure – they contained Celestion Vintage 30s.]
