Pre-shape

Recommended Posts

Just curiosity really, I have a Trace head, and always use the pre-shape. I read it boosts bass/treble and cuts the mids. Does anyone actually know the exact specifications of which frequencies it boosts/cuts and by how much, or is it a Trace guarded secret?

Cheers! :)

It's a straightforward question that deserves a straightforward answer, which is: +6dB @ 50Hz; –12dB @ 400Hz; +6dB @ 5kHz. From the Trace Elliot catalogue here: [url="http://www.traceelliot.com/catalog/catalog.pdf."]http://www.traceelli...og/catalog.pdf.[/url] Obviously not a trade secret then.

Why you are asking this ? Is it for academic purposes, or something else ? it may help to structure an answer to your question.

Why? As I said, for curiosity, as I use a Trace head and pre-shape, so would like to kow how the pre-shape shapes the sound. I can never quite replicate the pre-shape when it is off and using only the EQ.

Thanks for the link! To be honest, never looked at the catalogue before, as I didn't think it would have specs like this in it. I stand corrected!

I have experimented with the pre-shape. But to be honest, although it sounds great at home on your own it, in a live situation I am not impressed with it. My graphic is set almost opposite with the low mids boosted, the lows and highs are fairly flat with the graphic slowly being reduced after the low mids. For me this has revolutionised my sound and it really cut's through the mix. Of course you my slap a bit more than I do and want the pre-shape?

Hehehe...slight confusion here! I'm not aiming to set the EQ the same as the pre-shape and then use it like this, I simply wanted to understand what frequencies were being altered when using the pre-shape, and to achieve that, I was flipping between pre-shape+no EQ and EQ+no-preshape and trying to replicate it. Not being able to, I thought I would simply post on here and see if anyone knows how the pre-shape was...well, shaping! So thanks to Stevie for a nod in the right direction!

Just for info, I neither slap or finger, I use a pick. It is all personal taste, but I like the pre-shape sound, through a 4x10 and 1x15 (or sometimes a 2x10) rig. For any EQ, I tend to either balance between the pick ups, and/or use the actives on the bass (which is rare). For what we do, the pre-shape sound in conjunction with my bass works very well, and I and the other members of the band, like the overall sound. :i-m_so_happy:

It sounded good to me at low home use volumes because it gave me an 'impressive' hi-fi tone, but when cranked at a gig it was unusable.

I did this exact same thing with 2 Trace heads I owned and was *completely* unable to mimick the sound of the pre-shape.

I also liked the pre-shape sound, not for slap but also for pick playing. I try to get a similar mid-scoop sound now from my set up as it is my preferred tone, only using a boosted mids for certain things that need it.
