I got this Aria Pro II Magna Series 5er from eBay maybe seven or eight years ago. It's got a made in Korea sticker on the neck heel and I think it plays nicely. Over the years however things have started getting a bit flaky.
So...
Take one perfectly usable bass and put it on a bench...
Whip the machine heads off to replace with tasty "new" Schaller M4's with Made in W Germany stamped on them
Replace the bridge with a real new Schaller 3D5
Things got interesting at the pointy end. On offering up the Schallers we found that the collar is 12mm, while the originals are 14mm. To really make a mess, the holes on the head that the tuners go through are 15mm, no wonder the B tuner was broken. We made some sleeves with an appropriate ID and OD
I don't have a picture of the sleeves in situ because I forgot and it means de-stringing and taking the tuner out so you'll have to trust me they're in there
Once the metalwork is sorted, take the pups out, empty the control cavity and add the new controls
Put the new pups in. Why is nothing simple? EMG don't supply springs and the originals were chocked up with a bit of high density foam. Plus the new pups are smaller than the old by enough to mean drilling new screw holes, fingers crossed I don't go through the back... Mr Maplin saves the day with a box of 150 springs for £2.99. I only want 8 springs, but springs and P&P from the 'net is over a fiver...
Control cavity wired up, and I bet that you are all laughing at me now..
The poxy battery didn't fit!!!! Re jigged to get it all in.
Cleaned and restrung, the finished article
As a bit of a teaser, here is the old plywood body from my P Copy. A new eBay body and the neck are in the garage awaiting new paint, plus there's a pedal board in the offing, so watch this space as they say.
