Hi Guys I now have a decent soldering iron and a bucket of enthusiasm

I buy pre amps to increase the output of the under saddle transducer pickups I fit to the acoustic guitars I make (hobby builder) can I make a simple pre amp to just boost the signal ,no eq volume ect  must be 9v battery powered that I can mount  inside the guitar that's a simple schematic that even a novice can understand
Thanks

Sorry Mr J m fahey I read my last post and I seen to have given up before I have even started,I welcome your help and any assistance you can give will be most appreciated ,I joined the forum to learn about amps electronics ,I wire up all my guitars transducers preamps ect and have built preamps from kits but have never understood how or why they work ,and perhaps the little freedom amp should be my first proper project ,I have been reading posts to try to understand the basic principals as it has always fascinated me
QuoteSo, first task is to cut a rectangular opening on the side (say, 2.5"x4"), where now the power socket rests, and mount there a somewhat larger piece of 1/8" Masonite or MDF , with 3 holes for: power cable, power switch and fuse holder (2A for 119V ; 1A for 220V)
I'll post a drawing for you to play it safe.
Posting a drawing would be most appreciated  can i send you some small picture to se if the are the right components
there is a switch on maplin that seems to combine all three would this be suitable

many thanks

Hi this amp stuff has me a little concerned I have been trawling the net and this excellent forum
Question:
Is it possible (advisable) to connect some kind of resister in my guitar at the jack socket to protect me if the amp or the power supply or PA should have a fault?
Or is Is there some device I can place between me and the supply as some of the gigs I do , they have so little regard for the temperature of the beer I,m sure the integrity of the wiring is dubious possibly lethal! (like the beer)

thanks

The Newcomer's Forum / "help with a Freedom amp please "
December 03, 2009, 02:04:51 PM
Hi Guys and girls just joined the forum I have had several vintage amps and I have a question?I recently moved house and came across my old Mike Matthews Freedom Amplifier it's the 10" non battery version plugged her  in and "unbelievable "it sounds as great as it did the day I bought it .It take a while vto power down but I think it always did? I took it to a friends and he loved the sound but was concerned it had a 2 pin power cable so it wasn't grounded? I know its an old amp and if I,m going to use now should I get it converted to a 3pin grounded plug? And can I do this myself I build acoustic guitars so I'm relatively practical,any help most welcombe
Many thanks

PS Concerned about this switch of "death" that pervades the internet
