I just picked up a Swan Pro RCS20 in a trade for a guitar . Its a 20 watt combo made in small quantities by Bob Swanson in Colorado. Bob is a studio owner and sound tech, who builds these amps in 20 and 40 watt versions, in small quantities. I think Wildwood is the only dealer. TGPs Shovelhead (Don DiMasi)has one these SwanPro amps and gave me some input about these amps, as did a couple of other Gear Page members, but I made the trade that brought me this amp without having heard the amp, so I was really taking a leap of faith. The SwanPro got here today, so I thought I would share some initial thoughts after playing with it for a few hours this evening. Its an EL84 x2 combo, with Master Volume, Preamp Volume, and Boost Circuit. While it is a single channel amp, it has a very usable boost with its own level control, which is footswitchable. Once you get the volume and boost levels set up at compatible levels, you have two easily switchable sounds available with use of the footswitch. Find your basic tone and volume, then kick in or out of the boosted tone and level, with the footswitch for OD or lead tones... This combo has a 12" speaker, private labeled for SwanPro.. not sure who makes it for them. The combo cab is chunky and somewhat bigger than most 1x12 combos with top mounted controls. It has Master Volume, PreAmp Level, Boost Level, Low, Middle and High tone pots. Each of the tone pots offers a good range of impact and response. This is a versatile combo for rock and blues, with the ability to get great OD tones at low to moderate volume. It is also plenty loud for small gigs too, but it is still just a 20 watt amp with two EL84s, so pristine clean headroom is a bit limited, especially when you are really cranked up at higher volumes.. To my ears this amp has a punchy, rock-oriented voice that can range from vaguely Voxy to Marshall-ish in tone, but it has a nice warmth, and thickness of its own. It seems touch sensitive. and responds well to pick attack when you dig in. I played through the amp with both humbuckers and single coils and the character of each guitar came through well. When pushed hard with the boost engaged, this amp really grows hair. It can get pretty heavy and modern sounding. The Master Volume is very effective and works well with the amp's gain and boost controls to make this amp sound good at bedroom volumes, but I pushed this amp hard and loud this evening, and it really sounded great... BTW, there are some sound samples & videos at SwanPro.com: http://swanproamps.com/MP4_sounds.htm The SwanPro seems well built and thought-out. It is a cool setup for home use at low to moderate volume and it seems to have more than enough fire power for small gigs too. For me, this amp turned out to be a really pleasant surprise, and I have only spent a few hours with it so far, so I am sure that there is much more to discover.
