The Blue Express anyone?

[Catweasel]

Hi all,
Firstly, please accept my apologies! I'm a bit of a newbie to building guitar amps, although I've built a few tube hi-fi amps so I know the basics.

Anywho, I was searching around for a bluesey-type amp when I stumbled across the TrainWreck forum & all the schematic files(!), including 'The Blues Express' - sounds perfect! . So I did a search here but couldn't find any discussions on this design... am I in the right place?

I'm just trying to find out if anyone has experince of this amp - Ver. A5h and the variations - before I start with the dumb questions

Many thanks,
Steve

Hi steve

Welcome! I wish I could tell you that I have built this amp but I haven't. It does look interesting after looking at the schematic, kind of an EL84 Express/liverpool design with a lot of bells and whistles thrown in for good measure. It is also using a Concertina/Splitload Phase inverter instead of the normal Longtail PI used in the Express and Liverpool. The splitload produces less gain than the longtail and might help account a little for the "sparkling clean tone" So it looks like this thing has a TW preamp coupled to a PI that Fender used in some of their amps and a output section from a 18 watt amp. I am sure that if you decide to build it you will be able to find help here.

There is more info on this amp at blue guitar including a sound sample

Good Luck in your quest!

Hi Dana,
Many thanks for your welcome & reply.

I appreciate your explanation and the links. I actually found two documents on Blueguitar, one re. the Blues Express and for the 'Plus' version . Just need to print them out and read 'em.

Thanks again,
Steve

Hi Mark,
Thanks also to you for the links.

I had a look at the Ampage board but I couldn't find anything specific to the Blues Express using their search function... maybe it was just me

Once I've read those articles and if I have any questions no doubt I can just ask them here or on Ampage.

Cheers,
Steve

The search function at Ampage is useless. If you post a question, you'll probably get a response from Steve.
