Re: rockabilly tone
you have no idea how long i've been waiting for this question
rockabilly tone, more than any other tone that i've found, is a tiny bit of a lot of things. Slapback echo is a biggie, 99% of the time set for one quick slapback, then you got your spring reverb, sometimes a tiny bit of tremolo/vibrato, and in the case of the rev & setzer - a tiny bit of distortion
The rev & setzer DO use distortion, just not like some of the 'tards out there today. They use it WISELY, in that you can still hear EVERYTHING the guitar does, you get a meaner tone, more sustain, all the advantages of distortion, but it's not muddy in the very least.
rockabilly tones usually feature old fender, or gretsch amps, fender being the biggy. The most popular rockabilly player in my town uses a brown vibrolux with 2 original jensens & all NOS tubes. Treble is the biggy on all these amps, it should never be any lower than 8.
here is setzer's setup. It's all accurate & correct
1963 Bassman - 50 watts
- blonde Tolex with wheat grille cover
- 6G6-B unmodified circuit with solid-state rectifier (less sag than tube rectifiers)
- preamp tubes - NOS Chinese 12AX7
- output tubes - NOS Philips 6L6WGB or NOS Tung Sol 5881
- cabinet - 2 x 12" Celestion V30, 8 ohm, 60 watt speakers wired in parallel (4 ohm total cabinet load)
with 12 gauge wiring
Settings
- normal input
- volume 4 (up to 5 for heavier overdrive)
- treble 10
- bass 4
- presence 10
From TVtheWiredTurtle - "Brian is using either the Phillips NOS 6L6WGBs or Tung Sol NOS 5881s, the amp is almost 10 watts less efficient hence the earlier breakup of the power section coupled by the "gainier" Chinese tubes that carry a bigger voltage than most NOS tubes and many Soviet reissues. It's running cloer to 40 watts." and "The nature of the EQ in the normal channel is such that when the treble is dimed, the bass is slightly attenuated which cuts down on the speakers farting out in the lows - although the V30s don't dive up the ghost very easily."
LONG Guitar cable lead (no wireless)
Setzer uses long guitar leads for room on the stage, but it also has the effect of eliminating the super high frequencies that can get "ice-picky." From TV again " He uses such long instrument cables, the capacitance loading smooths out the high end harshness that would otherwise be killing the crowd when using mere mortal cables like we all use (10'-18')"
Putting it all together
The trick to the amp sound is to set it just to the point of breakup. With a Gretsch, that happens at 4 to 4.5. At that setting, you can back the volume of the guitar off to clean up the sound or dig in with the pick to get a more distorted sound. The heart of Setzer's sound is overdriven tubes. Pedals will not get you the same sound.
Treble is the name of the game. Full treble, full presence. The bass is rolled off mainly because of the sealed cabinet. Sealing the cabinet tightens up the bass response and too much bass will muddy up the sound. There's plenty of bass in the cabinet without adding more.
The only real modification to the cabinet is replacement of the speaker wires. Heavy gauge (12 gauge?) is used to bring more, unrestricted signal to the speakers. Really an important part of the sound. The speakers are Celestion V30s. That seems to be a widely popular choice for a rock sound. Nice breakup.
Live, Setzer always uses the Bassman, but in the studio, anything's game. Supros, blonde Showmans, Gretsch Cowboy amps, Princeton, etc... It's impossible to know what's what on his albums ampwise, but the basic sound is the same.
