Speaking of strings, I just learned that GHS' short scale strings are cleverly engineered to fit Hofners (the silk just clears the nut with a 32.75" winding length). This opens up a world of possibilities, like the yummy-sounding Balanced Nickels and Pressurewounds.
This afternoon, I took off my 2+ year-old La Bella Beatle Bass flats and put on a short scale set of GHS Precision Flats, and they're a nice fit (physically and sonically). The La Bellas had become a bit too thumpy--or maybe 'thunky' is the word--over time, and I was ready for a change. The GHS are perhaps not quite as creamy sounding (they still need to break in), but they do have a major advantage (in addition to not sounding thunky): I've always found the La Bellas to have some problematic honky qualities when blending the neck and bridge pickups, but the GHS Precisions allow for smoother-sounding blending. Dialing in the intonation, as always, was a bit of a pain (even though the La Bella and GHS gauges are similar); it's a real deterrent for changing strings on a Hofner, but it's all set now, with the bonus of the bridge being further from the bridge pickup, which improves the sound, too.
In the past, I've found that nickel-plated rounds and La Bella White Tapes eliminate the honk, too, but I don't like the feel of either of those as much as these GHS flats.
Although it seems like Pyramids and La Bellas rule the roost on Hofners, it's good to remember there are other options worth exploring, too.
