GDS 18W Amplifier: S/C Head

$1199 + S&H (MSRP $1500)
The 18W S/C head is bolder than a typical GDS 18W amp with more sustain. Try one for the latest in 18W tone and decide whether ‘S/C’ stands for ‘Single Channel’ or ‘SuperCharged’! The Single Channel head has all of the tone of a well tuned 18W but in a simple small package. You get all of the tone with no hassles, no questions and no compromises. This is 100% hand wired, eyelet board construction with only premium grade materials throughout. There is simply an input, volume and tone. Just leave the volume and tone at 5 - 7 and play. Two 12AX7 preamp tubes, two EL84 power amp tubes and one EZ81 rectifier tube. A 1-12 cabinet (with a Guytron Bigtone 35) can be added for an additional $545 (MSRP $699) plus shipping.
