any audiophile guitarists out there?

My brother owns a THD UniValve amp which has a clean and neutral quality.

here is a blurb from their website: The THD UniValve is a Single-Ended Class A amplifier head with a single output tube that can be switched at will among many octal-based power tubes...

Daveyf - Before I realize I have no talent for music I bought 30W VOX Valvetronic. It uses DSP processing to mimic sound of different cabinets but also effects. Non-distorted effects are pretty good but distorted are horrible. At the time I considered Roland Cube.

Kijanki, One of my modellers is a Vox Tonelab. It has the ability to model various amps, pedals, cabinets etc. I used to own a Line6 Pod v2, which IMHO is very limited and sounds much worse than the Tonelab. However, I have never used a modeller that really comes that close to the real thing.. i.e.,A Fender Tweed from the 50's has a tone that is to die for, the modeller's repro of this amp is really a joke when you do an AB.
I think if I were to get another amp, my #1 choice would be a Princeton or Deluxe Tweed folowed by a Black Face Super Reverb. All are amps that sound truly magnificent, IMHO.

Daveyf - I started with classical Cordoba R40 and took some lessons then bought Martin D15 to follow by used cheap Silvertone copy of Les Paul (changing pickups to Seymour Duncan Jazz and JB) plus mentioned Valvetronix and finally Ibanez Soungear SR300DX 4 string bass and 100W Carvin bass combo.

Now I don't know what to do with all this since I lost interest. I still play very simple classical a little and hope to start basic bass lessons but most likely it will all end-up in hands of my grandson (currently 5).

I agree that modeling doesn't come close to original thing. Fender Tweed was great but I thought once of finding original 30W VOX (that Beatles played). Tube amp with no feedback, Alnico magnet speakers etc. It amazes me that early rock bands played out with 30W combos while power now is often in kW.

Kijanki,
I would suggest that you go to a local guitar shop and play a Fender Strat or a Tele or a real Gibson Les Paul; Once you pick up one of these and play a few notes, you may re-consider. If not, well so be it, you will then notice that one of the nice things about good musical equip is that it holds its value very well. I would expect that you should be able to get back most, if not all, that you paid for the Martin, as an example.
