Ruby/Little Gem question

[ambulancevoice]

is it possible to use a little gem or ruby as a bass amp?
i was thinking of doing the ruby with the bassman mods and just do that
but if possible, i wanted to see if i could mod the little gem mkII to be more like a bass amp


and would either the little gem mkII or the ruby (with bassman mods, or without) be able to drive 4 X 10" speakers?

They drive low wattage speakers very well.  Look for high efficiency  - 95dB/W @ 1m or more.

As long as you use large input and output caps, there's no problem with bass.  Go for it.

best (and most cost efficient) 10" speaker i could find was an 87DB 1W/1m speaker

and by large value caps, you mean like 1.0uF or 0.1uF etc?

I took the below text from runoffgroove.com on the Ruby.  I tried this and it works OK for a personal headphone or practice amp.  I added a compressor too and this made it sound tighter.

Bassman
Replace the .047uF cap from the FET source pin to the volume pot with a 0.1uF. Place a 220pF cap from lug 3 to lug 2 on the volume pot. Remove the Gain pot and place 2k2 fixed resistor between pins 1 and 8. In this configuration, Ruby sounds very much like an old Fender Bassman to our ears. With the Volume control at half rotation and below, you'll notice smooth and sparkly cleans with good depth. With the Volume pot set high, you'll hear nice overdrive that is great for blues playing. The transition from dirty to clean can be controlled with your picking or strumming. This aspect can add an extra dimension to your playing.

yeah i know about the bassman mods

someone define a large in/out capacitor value
like 1.0uF? or something
