That's sound good cal, and the amp there's nothing like those old amps,
When I go to Guitar Center or Sam Ash I have to cover my ears because
the new amps sound so bright and tinny. :bang:
Bob,
Are you aware that Bernard is also a guitar player?
I love the older amps that have less gain. I find them to have a better more full clean sound and to be more "touch sensitive."
In my style of playing I don't add distortion to enrichen the sound, and any distortion only comes from the amp. Pretty much the sound comes from my hands, and I try to emulate a piano, but also try to play the guitar as a percussive instrument like a drum.
An amp like your 5B3 tweed Deluxe has the smooth breakup of 6V6 output tubes and highly interactive volume and tone control. The breakup is lower with a P12R than the P12Q you are using. Some say the P12R has a "farty" bass though.
Similarly I could add two P10Q's instead of the P10R's I'm currently using for more headroom and tighter bass. The smaller ten's over your single 12 though produces a wonderful bottom that is tight, but with a fast treble. The dispersion of 2 ten's also really fills a room, and creates a 3-D space.
The two Mark Sampson era (early to mid 90's) Matchless amps I own (a Lightning and a Spitfire) both have two-ten's instead of a single 12.
The Lightning is higher gain and the tone controls are very much like a "Blackface" Fender, but the Spitfire has a single tone control like your Tweed Deluxe that provides less scooping of the mids and provides a fatter midrange.
The Spitfire also is lower gain, making it my favorite out of the two. A lot like your tweed Deluxe in many ways. Both the Lightning and Spitfire both have the same "Voxy" 6BQ5 output section/tubes. Even cathode bias like your tweed running as a "Class A" amp and are claimed to be only 15 watt amps. The huge transformers that are overbuilt in a savage manner, the beefy power supply and the circuit denote a much more powerful amp.
The Celestian Greenbacks are aged and have had the "doping" removed by Matchless, so the sound is more open and looser.
I bought these Matchless amps as investments. Today I don't see any Mark Sampson era amps available, and when do they tend to be the bigger more powerful amps. Worth at least double what I paid for them, and perhaps if I found the right buyer maybe triple the price I bought them. The 2-10 configuration is not stock and is special order making them a rare version.
The Lightning also features an odd covering called "Black Shower Curtain" that adds an exclusive rarity.
I did a lot of "tube rolling" which is testing these amps and optimizing them with NOS vintage tubes.
Not unlike Leica but these German 12AX7's both "smooth" plates and "boxed" plates seem to be my favorite pre-amp tubes. Mullards are also interesting for the midrange, but the Telefunken's have the chimey top. Amperex "Bugle Boys" are kinda crunchy and thick.
I did this when I had a loft in the Southside of Williamsburg. This loft was terraced and had 14 foot ceilings that seemed to be tuned like a speaker enclosure. The acoustics were like in a mid-evil Church meaning perfect.
