THE IDEA - to evaluate how 3 of Stephen's amps sound through a number of different speakers/cabinets in the studio!
THE PLAYERS - My assistant Garret kindly played for me. We decided we would record one clean tone and one dirty tone from each amp through all of the cabinets I have at my disposal.
The amps: My brand new TC-15, and Stephen's v6 and JTM45 prototypes
THE CABS
Trinity Amps Marshall-style 2x12 (Tone Tubby Alnico/Tone Tubby Ceramic)
Orange PPC212 2x12 Cabinet (Vintage 30)
Mesa Boogie "Oversize" Recto 4x12 Cabinet (Vintage 30)
Hiwatt SE4123 4x12 Cabinet (70's Fanes)
Marshall 1960A 4X12 Cabinet (G12T-75)
Marshall 1960AX 4x12 Cabinet (G12M-25 "Greenbacks")
Marshall 1965A 4X10 Cabinet (G10)
Fender 2X12 Cabinet (60's Oxfords)
Peavey 1x12 Cabinet (G12 "Classic Lead 80")
THE PROCESS - All the clean tones on all amps were recorded using my Fender 50th Anniversary Strat (Custom '54 pickups) in the neck position.
All the dirty tones on all amps were recorded using my Gibson Les Paul Studio Vintage Mahogany (Burstbucker Pro pickups) in the bridge position.
Before recording, I set the tones by tweaking in 3 or 4 cabs. I was looking for tones that would work across all of the cabs. Once I had settled on the tones, and started recording, I didn't touch a knob. Obviously, it would be possible to tweak the tone for each cab, but what I was trying to do is reveal the different characteristics of each cab, so for the sake of comparison, the tone couldn't change. I used a single Shure SM57 microphone pointed directly at the edge of each speaker cone. I measured to make sure that the distance from the grill to the mic was the same for each amp (I didn't account for the fact that the speakers could be mounted in each cab different distances from each one's grill, but I'm not going to lose sleep over that!!). I used a Neve-style Vintech pre-amp, and then went straight into my Mytek A/D converters with NO processing. The only thing I did after the fact was to balance the level of each clip (using Waves L2) so listening wasn't influenced by differences in level. The L2 applied NO limiting.
Notes on the clips – We ran out of time on the TC-15 clean tone so pardon that ommission… Also, in the TC-15 pic, it looks like we were using Ch.2. We were not. The TC-15 tone was the Ch.1 EF86, "Lo" input, "munch". We recorded dirty 18W tones using both the EL84 and 6V6 output tubes. The 18W clean tones were EL84 only.
Enjoy and be sure to vote for the cabs/speakers you like best!
