The rear of the headstock has a small CFS decal, which I believe means "circle fretting system" which may indicate a Fujigen product. It also says "Made in Japan" and has a serial number. I'd like to know more about this bass, i.e. who made it and when. It's a quality built instrument, wonderful tone and playablility. Thanks in advance!

[color=#333333][font=Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif][size=4]I recently picked up a Polytone Mini Brute (model Baby Brute - Teeny Brute year 1981) that is wired for 110v. I wish to convert it to 220v. I have the schematic on how to do so (see link below), but I am having trouble locating the connector referred to in the directions. Anybody who has been thru this conversion process please help out! Thanks in advance.

I recently came across a double bass with extensive dragon-themed mother of pearl inlay thoughout the entire face. The bass appears hand-made due to the primitive work on the headstock. The tuning machines are rather poor quality. The bass probably spent a lot of time in Vietnam but I am not aware of any Vietnamese luthiers making double basses. Any help identifying this bass is much appreciated. See link to photos here: http://mekongguitars.blogspot.com/ Thanks Basschat!

I am looking for advise on the best way to increase the performance on my small collection of low-end bass amplifiers. I've been told that increasing the value of the output capacitors in one of the best bang-for-the bucks. For example, my Hartke B60 (60W, 12 inch) has a pair of 50v 4700uF cap's. I thought I'd wire in parallel with the existing cap's a couple of 50v 10,000uF caps, which effectively triples the uF value. Is there a max/min uF value one needs to keep in mind? E-Bay has inexpensive electrolytic capacitors available from China, Korea etc; has anybody has experience using these components? Also, I am often appalled at the thin (cheap) wire that manufacturers use to wire the speaker driver on combination amp's. If I replace the speaker wire with something thicker, should I replace the wire back to the trace on the pc-board (as original) or follow the trace back to whatever component is driving the speaker ? (I assume the output transistors). It seems to me that the pc trace could be the weakest link in the chain between the amplifier output and the speaker. Sorry if these topics have already been adressed on Bass Chat, but I couldn't find anything in my search. Thanks!

Thanks so much for the feedback. I will try the Heavy Strings for a while. If that fails then I'll make myself a jig and apply light pressure for an extended period of time. Cheers!

I recently acquired a Yamaha BB-V MIJ bass that had spent an unknown amount of time with no strings attached and with the truss rod tightened down quite a ways. Consequently, the neck is bowed backwards. I released the truss rod nut all the way, and strung up the bass, let it sit for a week. The neck came back a considerable portion but still has a way to go before being playable, and I think that all I will get with string tension alone. I see various videos on YouTube regarding neck straightening, although only for necks banana'ed in the usual forward direction. If anyone can give me advise on how I can resurrect the Yamaha neck, I would very much appreciate it. Sorry if this topics is already addressed but I couldn't find anything. Cheers Bass Chat.

My local music shop has for sale a Made In Japan Yamaha Super Bass 600, serial number 001226. Per my research so far, the leading zero indicates year built, which I assume to be 1980. Tobacco sunburst finish, fair to good condition. I can not find any information about this model bass on the internet. I am hoping to get confirmation on the year built, and if the $250 USD asking price is reasonable. Thanks in advance Basschat!
