I know a guy who owns LF, I could phone him up tomorrow and ask for gutshots

...resistor values are confirmed - 110k, 30k, 8k2, 470R

Volume pot is 250kB in the unit inspected by my friend. Fuzz pot is stock 1kB. Alpha brand

Transistor brand unknown - sanded marking, voltages to be fallow

Output cap is 10nF - AFAIK it's early issue, so MJM could change it in later units. Two remaining caps are polarized e-caps, values to be fallow

Input cap is marked 1u5 (reads 2u4 on DMM), the cap across fuzz pot is 15uF

Those are values from older or newer LF?

Older, quite lousy made BTW... Mixed resistor type, bad wiring routing, pos in overal.

I'll get the picts on as soon as my kid will pop up to bed

It can sounds cool, but looks shitty.
I don't get it - why they were using different type of earch parts?!

For mojo, HAHAHA!

Actually, my friend thinks the parts ware sorted for value, I don't think I believe it, but who knows

Q2C is high, and overall unit is PITA in use. Before gigs my friend is chilling it in fridge. I guess it's leaky as hell

LOL!

I found gut shots one of more recent units - looks much better now, but still they're using different type/size components...

beedotman · Post by **beedotman** » 08 May 2013, 10:23

And here's is another 'new' unit - again, different components...

And another one!
