Scottone had me over at his place to demonstrate his new Stephenson 30 combo with power scaling. This amp is from British Columbia and is made by Mark Stephenson. It has a toroidal power transformer that keeps the amp quiet, power scaling, four power tubes that can be switched in or out of the circuit (two of the power tubes are octals and these sockets can take almost any kind of octal tube that you can dream of since the amp is cathode biased). The two other power tubes are EL84's. The amp has a special output transformer that copes well with the grouping of different power tubes. The amp sounded awesome with just one EL84 running cranked up. If you need more power half ways through a gig, just switch in another power tube. The clean sounds have a huge of tones since you can combine any tube combination that you can dream of. But the mix of two EL84's with two 6V6's presents the tonal characteristics of both tube families, and since these tubes are different, there is less cancelling of even harmonics, according to Stephenson's literature. Well this combination does chime. Imagine changing the tube settings for the acoustics of the room and loudness. It's a great sounding amp and if switching tubes in and out is not enough, power scaling is there for extra breakup. Scott is very happy with the sound of the amp. I brought along my string of pedals and the amp worked very well with all of them. Even I was there for a couple of hours, I was only able to scratch the surface of what this tone machine could do. You can get pure overdriven output tone at low volumes and loud cleans just by the click of switches. Billy Talent's guitarist Ian uses Stephenson. I really like this thing because of the possibilities, and my tastes for tone change from day to day. Think: pure EL84 sound, pure EL34 sound, pure 6V6 sound, pure 5881 sound, Pure KT66 sound, pure KT77 sound, or combinations of all of the above. Did I say that the amp is point to point and built like a Rolls Royce. It has switches to change radical amplifier settings such as ultra linear etc (don't ask, I'm just learning). Thanks Scott for the Gas, I think I want to buy one. Scott is an awesome guy and knows amplifiers.
