THE ULTIMATE LOW-WATT
INSTRUMENT AMP
Price: $2,700
Simple to use. Wide tonal range. Clean to cranked distortion textures. The STUDIO-10 is similar to the very first production STUDIO amp model - which was also the first production guitar amp with Power Scaling.
The design has been updated with a 2-way EQ in the preamp, separate BODY controls for each power tube, individual T-U-P switches (Triode/Ultra-linear/Pentode), MATCH/MUTE switches for each of two separate speaker outputs, DAMPING to control speaker bass tightness, SHAPE as a low-frequency contour and SPARKLE as a 'presence' control. POWER SCALE allows power output to be varied from 10W down to milliwatts - over 40dB of dynamic power range.
TWEED-MIX-MODERN provides the round sound of old cathode-biased amps, the fast and punchy sound of new fixed-biased amps, or in-between sounds.
The preamp and power amp can be used separately, or with line-level effects between them using the rear-panel PRE-OUT and PWR-IN jacks.
A Line output tracks the speaker sound, and can be used instead of a speaker for silent recording. Balanced and unbalanced lines are accommodated via transformer isolation.
The STUDIO-10 is very low noise. We've retained the passive multiple choke filtering of the original model. Heaters are DC and isolated. Polypropylene filter caps assure a wide frequency response for the supply, complementing the custom toroidal power and output transformers. Both transformers have core bands and plate shielding, and the PT has an electrostatic screen to isolate mains noise.
STUDIO-10 is built in a 2U chassis with power tube access via the rear panel. Meter and bias adjustments are also on the rear panel. Preamp tube access is via the top cover. Approximate wight 11kg. The preamp accepts any of 12AT7, 12AU7, 12AX7, 12AY7, 12AZ7, ECC81, ECC82, ECC83, or their equivalents. The power amp can operate with a single tube, or two that are the same, or two that are different. Any of the following types or their equivalents can be used: 6CA7, 6L6G, 6L6GB, 6L6GC, 5881, 6550, 6550A, 6550B, 6550C, El-34, KT-66, KT-77, KT-88.
World-wide mains compatibility is available via the rear panel RANGE switch. Set it to 115V for any voltage from 100-140V, or to 230V for 200-250V.
If you need more power, a more sophisticated preamp, front-panel access of tubes and bias, and advanced power control features, check out the STUDIO POWER AMP and STUDIO PREAMP.
