Soldano SLO 100 and SLO 30 mods
A more lively and dynamic SLO...
Exclusively for the later model "BAD" SLO 100 and SLO 30.
A juicy, harmonically rich SLO, with added tightness and more usable gain. Turning the gain past 5 or 6 has always been a challenge without too much bass and lack of definition on a stock SLO. Turn the GZ SLO up to 10 and it remains composed, with tons of clarity all the way through the range of gain.
The clean/ crunch channel is also tweaked to better match the more dynamic and tighter response of the high gain channel.
No holes drilled for the mod.
Added front panel features
Features included with all SLO 100 / 30 mods:
A "Pull Gain Cut" feature added to the bass control adds a lower gain, more open texture to the higher gain channel. Great for getting into more of a rock or blues type territory.
"Pull SAT" on the treble control adds a diode clipping circuit for more saturation and a higher gain feel.
Rear panel features
Using the factory line out holes, a negative feedback "(-) FB" control and a 3 way depth frequency switch are added.
The (-) FB control adjusts the response of the power amp section, giving a much wider palette of tones from the circuit. From dark and smooth, to brighter and more aggressive and raw.
3 way depth switch changes the frequency response of the depth control on the front of the amp. One setting is stock, the other boosts the mids and the third setting scoops the mids.
