Evolution of Hi-Gain Pickup Cover Cutout
I'm rebuilding a 660MG and decided to put Hi-Gain pickups in it.
Long ago I researched when the Hi-Gain pickup bobbin went from the flat fiber-top to the plastic molded bobbin. See: viewtopic.php?t=404086. That change happened around August of 1991.
Now, when I bought two of the old fiber top pickups, I noticed that the shape of the inner cutouts of the covers were not identical.
One had straight sides and the other had curved, sort of barrel-shaped sides.
I'm starting to research when the change from barrel-shaped sides to straight sides happened.
So far I see that current Hi-Gains have straight sides and so do the ones back to 1990. Ones from the 70's have the barrel-sides.
Does anyone know when the change happened?

Re: Evolution of Hi-Gain Pickup Cover Cutout
Looking through the Register, it looks like the switch to the straight-sided cutout happened around July or August of 1988.
This is a 620 from July 1988: http://www.rickresource.com/register/us ... llsize.jpg
It's barrel-sided.
This is another 620 from July 1988: http://www.rickresource.com/register/vi ... p?id=37686
It's also barrel-sided.
Here's a 330 from July 1988: http://www.rickresource.com/register/us ... llsize.jpg
It's barrel-sided.
Here's a 330 from August 1988: http://www.rickresource.com/register/vi ... p?id=20016
It's straight-sided.
Here's a 330 from September of 1988: http://www.rickresource.com/register/us ... llsize.jpg
It's also straight-sided.
This is from January of 1989: http://www.rickresource.com/register/us ... llsize.jpg
It's also straight-sided.
Anyone have another opinion?

Re: Evolution of Hi-Gain Pickup Cover Cutout
I agree. My hi-gain covers on my 320JG and 360-12WB FG ckbd are older, @ 1981, and the interior bobbin sides are not symmetrical. this leads me to believe they are ground-out toaster covers.

Re: Evolution of Hi-Gain Pickup Cover Cutout
I've been wondering about this for a while. I have a 620 with one of each!! Bridge is rounded and neck pickup is straight. Dunno if you can see it in this pic.

Nick: What's the serial number on your 620, please?

7143
Funny, I've been meaning to ask about this for the last five or six years and I have a lull at work and log in and the topic comes up.

There should also be a letter and a number above the jack.

My next guess would be F4 from June 1991.

I think so! Mind you I think 620s in general are priced at much less then their true worth...nick_st_hilaire wrote:Ha ha. Yes H1. I thought I got a great deal.

That guitar's great support for the dating of the changeover!
