I just bought a Thunderbolt and was wondering if upgrading from the OP-24 to the Optima would be a good investment. Thanks.

Someone once told me that the Optima is pretty much the same as the OP24, but repackaged. I don't know if it would make much of a difference at all, especially considering the $275 or so that you'd pay for a new Optima.

Not true.

OP24+C draws more power (6mA vs. 4.7 mA)
OP24+C has higher distortion (.3% vs. .1%
OP24+C has 3 band EQ vs. 4 band EQ
OP24+C has Prehape and Midshift vs. Notch Filter

I am a huge fan of Optima, but some people feel that the OP24 has a "warmer" sound.

Day-um Tup, that's some great info.

Is there a comprehensive pre-amp comparison chart anywhere on the web?

It'd be nice to have the 'footprints' also!

It took me 30 seconds of work on the ovation website.

As shitty a job as they have done with the guitar info, they actually have done a VERY nice job with the electronics section of the website.

I have T-Bolt and had an Optima installed in Feb.
I love the balanced line out.

Pez,

did you have the work done at the factory? did they have to move the output jacks? thanks.

Yup It was done in New Hartford.
The 1/4 is in the same place
The balanced line out is next to it.

You will love the new battery box with sliding cover. So much easier.

Oh ya the onboard tuner is simply a great feature too.
OP-24 is excellent system sound wise.
Optima is leap ahead.
The balanced line out has at least 3 times the output.
I had my T-bolt since Aug 15th 1989.
I had no regrets in the new preamp.
