I would like to try this with a Zinky Lil smokey amp, after all he's my freind from Flagstaff.

Hi Mark,

 

I have done it a few times - seems a shame not to use up some of the space in the box :0)

 

 

 

 

 

 

 

Sticking the speaker to the back of the box seems to make the piezo feedback less.  Also due to the size of the speaker and 9v battery supply I decided that it was mainly for the player's benefit so stuck the last one on the side of the box so the player gets the most volume.

 

I tend to screw down the box lid so to make changing the battery easier add a battery box - cheapest ones I have found are from http://stores.ebay.co.uk/CharliesMusicShop search for "Dunlop battery box" the direct link is here http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=1604957063... until it is relisted.

 

Regards,

David

Very good sdtuff David.

It looks like a good idea to mount the speaker to the back of the box.  If it could "float" on a spring or bit of foam it would isolate it from the guitar body even more.

It looks like you are using a preamp with some EQ controls going into a mini-amp? Yes? What brands/models are these?

 

I used a small decorative brass hasp with pivoting hook to close the box so I could get in and change the battery or tinker.

 Hi Mark,

Thank you for the interest.

The preamp on the top one is a takamine I picked up off ebay and the miniamp is a 3W kit from Maplins (UK)http://www.maplin.co.uk/module.aspx?moduleno=2904.  It works well with the magnetic pickups but the piezos like to feedback if you crank up the volume too much.

 

The middle guitar is a kemo 3.5W universal amplifier module  http://www.maplin.co.uk/Module.aspx?ModuleNo=37734

the easy way to add an amplifier

 

The bottom guitar is the same preamp kit as the top one.  The piezo is a great find off ebay from China/Hong Kong listed as a "passive Preamp" - in reality it is a prewired kit that has a piezo undersaddle rod, passive volume and a passive tone that actually affects the sound of the piezo and an output jack socket.  I rate these highly - I have recently just added one to a classical guitar and the piezo picks up so little extra noise and gives  zero hiss unlike some active preamps.  Also it can tolerate effects at a much higher level before you get feedback.  I posted a few pictures previously http://www.cigarboxnation.com/group/cbgwiringelectronics/forum/topi...

 

Regards,

David
