Plans are great and normaly most of people don't really need more informations, but i love write reviews of bass, effect, amplifier, make pictures, talk about DIY...
I take approximalty 200 pictures of the making of the O15TB. Actually i use this cab with a Hartke HA3500, but not the standard version because i already make somes upgrades.
You can see i love screws

For informations, the paint come from blue aran "Tuffcab". Really great finish with it.
































From the beginning







I REALLY love this cab. It's simply the best i try. Sound is very neutral and my opinion is this cab respect all subtility of playing, and the instrument.
I add the attenuator for the tweeter and i think it's a good idea, because with somes bass, the sound is really clean. Just a little less treble is something nice. But i don't hear buzz or something else, Bill make a really nice work

Bass range is very clear and deep, just perfect. The accuracy of each note is real, and no problem at all to play with a good sound at the end of the neck. For exemple it's the same thing than plug a Dingwall and hear the accuracy of a B string ! ( i really need to check with a Dingwall this setup, but it's another problem

Harmonic are great, chords don't sound rough, each notes just sound good. It's just like a Hi-Fi system but for bass guitar.
A five string with B string sound BIG.
For me, it's actually the best setup i tested. Just the sound of the bass and nothing else, it's not an Ampeg

Somes others pictures of the making i put a link, when i finish the tutorial.
Thanks Bill
