Hamer CH-12 Chaparral Bass
The Hamer CH-12 Chaparral 12-string bass was introduced in the summer of 2000. Cosmetically it is identical to the Hamer USA model B12L but the features and construction have been trimmed to reflect its lower cost. The CH-12 sells new at retail for about 30% of the B12L. Originally the CH-12 was made in Korea but production was subsequently moved to China and then Indonesia. The Korean basses are generally accepted to be the best quality CH-12's.
CH-12 White Pearl
The White Pearl finish was available on the Korean basses, but all Chinese and Indonesian 12's are black.

Pekka Ranta's CH-12 with Custom B12S-Style Body
The neck, pickups and hardware are from a black 2001 Hamer CH-12. The alder body was made by Marko Ursin in Finland. The finish was produced by putting mahogany stain between nitro coats. The original CH-12's active electronics were removed; now the pots are just volumes for each pickup.
When asked about the sound of the different body Pekka reported, "Well, the sound is rounder and the harshness with the old bridge pickup location is gone. The front pickup is in the P-Bass position and when the bridge pickup is soloed you can spot a bit of a Sting Ray sound there. When both are played together the sound is more mellow. I actually thought there would be much less tonal variation. Of course I didn't or can't do an A / B test with the old body but the new body resonates better and is a bit louder and open sounding when played unplugged."
"The reason to ditch the preamp was that I prefer to tweak the amp and pedals. The very main reason to change the body was of course the looks."

The work was done
by GMW Guitars which is the Jackson / Charvel custom shop. Everything but the
face of the headstock was stripped.
The back of the neck and headstock were left natural.
The pickups were replaced with EMG-40 soap bar pickups and a BTC active tone circuit was added.

Hamer CH-12 Ad:
"The Chaparral 12-String Bass is designed after its cousin the Hamer USA B12L, with a Maple neck and a Mahogany body. The set neck features two truss rods for a stronger and truer neck. Two humbucking pickups provide sparkling highs as well as all the bottom end you'll ever need. Active tone pots and a pan control provide custom sound tailoring. The bass features the four fundamental strings with the octave strings doubled for incredible sounds."
Although both the B12L and
CH-12 should have stereo jacks, that does not mean that they have a stereo
output. When correctly wired, the ring of the stereo jack serves as a battery
disconnect for the active electronics. Plugging your cord into the jack turns
the active electronics on, and removing the cord disconnects the electronics and
preserves the life of the battery. So the jack is stereo, but the output is
mono. The first shipment of
Korean Hamer CH-12 basses was
shipped with incorrect mono output jacks. These jacks cause the batteries to
become completely drained within a very short time. Check
here for instructions on how to correct this
