Michael is available for online lessons via Zoom, and 'in person' & remote session work.
Pick up 'The Michael Gregory Band - Guitarchitecture' to hear more of Michael's amazing guitar playing.
To demonstrate the absolute noise levels of all of the amps in this series, no noise reduction or noise gates were used. No EQ or compression was added during the mixdown. You are hearing the raw, unprocessed sound of these amps (except for the horrible audio compression that the UA-cam bots thought would sound good).
Michael Gregory had no idea what guitar amps he was going to demonstrate when he walked into the studio the day of 'filming', so if you see him fumbling around with the controls, these were his natural first reactions.
SIGNAL CHAIN:
Guitarist: Michael Gregory
Guitar 1: Ernie Ball / Music Man LIII Steve Lukather model
Guitar 2: Fender Telecaster (Mexican) w/ Seymour Duncan Antiquity (50's era PAF replicas) humbucker pickups.
Amp: VOX AC30/6 TBX w/ 'power scaling' modification
Left Speaker: VOX Celestion Alnico Blue
Right Speaker: Celestion Vintage 30
Amp Valve Compliment (from left to right):
Vib/Trem: VOX (stock) ECC83
Vib/Trem OSC: Ruby 12AX7A

Phase Inverter: Unmarked (suspected RCA) matched for balance and selected for tone and noise.
Power Tubes: Russian EL84
Rectifier: VOX (stock) GZ34
Guitar Amp Recording Chain: Senheisser MD409 (on each speaker in the AC30 cabinet) → API 312 Mic Pres → Neve 1073's (EQ's bypassed). (No signal processing was applied during mixdown)
Michael's Lavalier Microphone: Audio Technica MT830R. This microphone blended with the guitar amp mics and provided a little bit of ambience. We chose to leave Michael's narration a tad bit low, as to not create an overabundance of ambiance, and also chose to leave this microphone unprocessed, without EQ and compression.
Patrick's Microphone: Shure SM7b (this mic was completely ducked by the guitar amp mic to keep the quantity of mics to a minimum while you hear Michael playing)
Love AC 30’S and 15’s. Keep these videos coming!
I play 3 hour gigs with this exact amp and never had any issues with it overheating. The ac30/6 tbx is definitely one killer amp.
We regularly use this amp on '11' for 8 to 12 hour sessions, in a small amp isolation room. While it never overheats, the tubes get really hot. So the combination of heat, vibration and small, enclosed environment for periods far beyond 3 hours could be why we were changing power tubes frequently. Once we took the tubes out of the 'torture chamber', we are now changing power tubes every 5 years instead of every 3 months.
Good demo, thx
I got to check out an AC30 from about the same period when my band’s other guitarist was putting touches on some of our songs in a friend’s recording studio. We ended up using my 65 Amps Marquee with its Selmer derived TMB channel on the tracks, but it was a close 2nd behind it, and was a lot more of what we were looking for over the Silverface Super Reverb, but the Marquee slightly out Hank Marvined the AC30.
I agree. The AC30 is definitely not the end-all-be-all amp out there, but it does get used on A LOT of recordings around here as a reenforcement amp. It seems to bring the guitars closer by about 5 feet when slightly blended-in with other amps.
The eq only works in the top boost channel
A lot of people are commenting on the EQ controls, so I'd like to clear the air about why knobs are being turned and not doing anything.
When we shot these videos, Michael had absolutely no idea what amps he was going to be demonstrating. We deliberately did this to get his genuine first reactions to each amp as he plugged into them. Consequently, this led to an obvious misunderstanding of the functions on some amps, leading to him turning knobs that do not function for certain channels, like the tremolo/vibrato and EQ knobs. We chose to not edit-out the obvious because we believe this adequately demonstrates how user-friendly (or not) each amp could be.
@@velvettonestudios4914 Don’t get me wrong, it took me some years to discover this on my own ac30tbx🤫
Awesome amps
I still have my 1999 Marshall made TBX.
Who did your power scaling mod?
What a great sounding amp !
When he "opened up the treble a little bit" while plugged into the normal channel, did it do anything? I'm not familiar with the TBX models, but with the AC30 I have, the EQs are not active for the normal channel at all, only the cut works.
6:35 how are you playing that???
I believe he's tapping harmonics with his right hand while fingering notes with his left hand....
Velvet Tone is correct 😊
normal channel = volume + cut only, brilliant channel = volume + bass + treble + cut. those bass and treble knobs do absolutely nothing when you are only plugged into the normal channel.
We've had this amp for 20 years, you'd think I would have learned it by now. It's always seemed like an odd setup to me that the normal and trem channels removed some EQ controls. Thank you for the clarification!
@@velvettonestudios4914 yup! it's a killer amp. the Top Boost circuit (including the extra 12AX7 and the tone stack) was originally a factory add-on installed on the rear of the early amps. In later 60s models (and the TB6 reissues from Korg), the original "Brilliant" channel was replaced with the Top Boost channel which includes the tone stack.
Fantastic 😍💋 💝💖♥️❤️
Thanks 🤗
