Thanks! The first knob is a master volume and the second is a cut control. The master is post phase inverter. The amp is still two channels but with a single input per channel and they are side by side on the left side of the amp. No sound samples yet. I am currently recording with my band and I’m using this amp so there will be examples from that. I have a web domain but no web site yet. I will start working on that soon and then I’ll need dedicated samples and some much better pictures.

I started building amps a couple of years ago and really enjoyed doing it. I started taking them to all my gigs and then sold all my other amps (aside from a ‘62 Concert). Then one day after a gig I was approached by a guitarist that wanted me to build him an amp. Hmmmm, so I do it or not? Well I did it. First I got business insurance and an LLC then I got to it. A few weeks later I sold him an amp and Southbound Amplification was born! The Cypress model is what he bought. It is based on a 6g3 only channel one is cleaner and two is dirtier. There is also a master volume, a cut control, a negative feed back switch and a boost for channel two. The picture is the amp he bought. I have a Cypress amp that looks like this too, which I gig with but I don’t have a cut control on my amp. I really don’t think it needs the cut control imo. I’m still experimenting with features and design for what I think is the perfect 6g3 type of amp. This amp has the ability to run either KT66 or 6v6 tubes for 30 or 20 watts. With KT66 tubes and a Alessandro neo GA-SC-X speaker the amp weighs in at 25 pounds which is still portable. I added test ports to rebias the tubes without having to pull the chassis. The switch in power tubes does require a rebias since it is a fixed bias amp and the transformer I’m using supplies a switchable voltage variation. The KT66 tubes sound really good in this design. I’m super excited about building amps and have other models I’m working on with more and less wattages. Who knows if I can make it a successful business, which for me would be just a small supplement to a retirement I hope to take in a couple of years.

If that is a crack I would be apprehensive about the guitar because it looks like it runs through all the mounting holes on the right side for the bridge, the string retainer and the Bigsby. Idk is $2700 is high for a perfect guitar but one with a big scratch I think it is and if it a crack it is way too high. As for the color, I love the blue and gold and the inlays are lovely on the fret board.

The first thing I do is remove the pick guard on a new guitar. I cannot stand them, they are in my way. One thing I like about a carved top guitar is the room it gives my fingers and pick guards take that away.

Oh yeah, the catering gigs just come pouring in after that!

Let me fix what I said. I bend up a whole step not an octave! I would love to be able to bend up an octave but…….

Oof! 14s are some heavy hitters. I run 13s on a ‘47 Epiphone Triump but I don’t really bend strings on that. For an electric archtop with a cutaway I use 12s with a wrapped G. I can still bend the e and b strings up an octave with that gauge. I have no doubt that 14s sound good though, I’ve always been a fan of heavier string sound.

Ha! It’s all the free dinners at the gigs that really helps to put the big bills in the pocket.

If you have a 4x12 and a 1x12 with the exact same speaker used and they are running the same ohms (let’s just say both cabs are 8 ohms) then the volume will be close for both cabs. The sound will be very different though because of the big cab and all that surface area of the speakers. The big cab can keep the low end together and put out a lot of it. The 1x12 speaker is working 4x harder than any one of the 4 in the big cab so it will sound very different and have a harder time keeping the bass as tight as the big cab. Though the volume will be close to the same if not the same for both, the way your ears perceive the sound makes the big cab feel louder.

A speaker that is rated at twice the amp power rating has long been the safe standard, or the combination of multiple speakers equaling twice the rated power. I personally don’t think that is really necessary though. I have now built 3 6g3 amps and paired them with 65 watt Scumback M75 Speakers. I would use lower wattage but there isn’t one until you get down to 25 watts. The amps have varied in output based on the power transformer used and plate voltage supplied. The lowest wattage of the three was 12.9 clean and 17.4 cranked all the way up with 355 volts on the plates. That would be fine for a 25 watt speaker. The first one I built I used a vintage spec PT and had 440 volts in the plates which gave almost 30 watts when fully turned up, that would not be good for a 25 watt speaker. So from a manufacturing standpoint, a company would spec a speaker that can cover variations like that. Smaller builders may have much less variation or can even spec the speaker based on a single build. I’m comfortable with a speaker that is around 10 watts more than the amp is rated for something lower wattage like a 17 watt amp. I built a JTM 45 that maxes out at 42.78 watts (JTM 42.78?) and I’m comfortable using the same 65 watt M75 in that amp but I probably wouldn’t go lower than that. The last gig I used that amp on I had a 200 watt Eminence Em12n speaker and it sounded great, especially clean. There is zero speaker breakup but the dirty sound is just a little sterile compared to the M75 that gets a little breakup and adds some warmth to the sound. Some may prefer the 200 watt speaker though, to each their own. The amp has a master volume and I turned it down to the level the sound guy wanted, then when I got home I measure the output. I played the gig at 14.5 watts dirty and about 8 watts clean with a 200 watt speaker. 8 watts with an efficient speaker is louder than most people realize and with todays stage management makes amps like the JTM 45 obsolete without a master volume or attenuation. I have a 20 speaker that is going into yet another 6g3 variant I’m building only this is a single channel and uses 6k6GT power tubes and should max out at 10-12 watts and be perfect for most places I play.

It is recent and on the custom core models only, the standard models have the original size head stock.
