Swart AST Pro Combo Amplifier, Dark Tweed
The Ultimate AST 6V6/6L6 - Designed in conjunction with guitarist Greg V, this is the no holds barred answer to the professional musician's need for an AST built for the road but without any loss in Swart style and élan. Introducing the AST PRO, which offers everything the AST is famous for, plus the following mods:

• Deeper Cab w/Recessed Chassis for Protection
• Chassis Elevated to accommodate Larger Speaker
• Celestion G12H-30 ~ *Anniversary Version
• Celestion GOLD 12 for that amazing Alnico Sound
• Rear Panel w/Switchable External Out/In & Enlarged Port
• NEW! Rear Panel now includes Night Light Input!
• Dark Lacquer w/Dual Piping & contrasting Light Grill
• Extra Large Rubber Feet for Vibration/Protection
• 15 1/2" W x 10 1/8" D X 18 7/8" H ~ Weight @ 31lbs

So what does this all mean?

Well, sound-wise, you're looking at the G12H30 Anniversary. The Anniversary version, perhaps *our current fav, seems not quite as stiff.  It's a matter of preference. The AST PRO sounds a tad "bigger" than the AST. The cab is 3/4 an inch deeper to allow the recessed chassis for additional knob/switch protection. This might add just a bit more heft to the bottom as well. The enlarged port in the PRO panel, now standard on all AST, gives a slightly more open sound. And the new switchable external output makes it easier to drive another cab, bypassing the internal speaker (8ohm output).

Looking for the famous Alnico sound? Then consider the AST PRO ALNICO which is the creamy breakup ultimate. We had been using the Celestion Blue, but at 15w, the Blue is a more fragile speaker. We have found the Celestion Gold to have most of the low level tonal quality of the fabled Blue, while surpassing it at higher levels where the Blue can sometimes lose some control. If you are looking for the signature Alnico sound that many love, the Gold is a great option within the AST Pro. If looking for the ultimate headroom with something like the 6L6 family, you might prefer the G12H-30s.
