| MODEL 1524 SUPRO DUAL-TONE CUT-AWAY | | | | | | | | |
| Electric Spanish DOUBLE-UNIT Guitar | | | | | | | | |
| This is probably the best Spanish Electric Guitar value ever offered in this price range. The offer has been made possible through our constantly improving production efficiencies being realized at the Valco factory. The highly efficient switch system enables the player to have instant response for either “takeoff” or “rhythm” with but a flick of a finger. The output power and tone of the two units can be accurately preset and then forgotten for balance of an evening of playing. Top two knobs are separate Tone and Volume for front unit. Bottom two knobs are separate Tone and Volume controls for rear unit. Units are electronically separated to avoid undesirable and confusing interaction. Easy to set and the peak of simplicity to play with outstanding effectiveness. We sincerely believe the pickup system to be the finest we have ever produced in over two decades of electronic development. Make an honest comparison with any instrument for tone, volume, and performance – you’ll truly be surprised. | | | | | | | | |
