RecPro Audio Pultec EQP-1a 2020 Demo:

Here's a new track recorded over April 2020, "This Shall Pass" written by Obie O'Brien and Cole Redding, engineered and produced by Obie O'Brien, and mastered by Phil Nicolo at Studio 4.

The recording was a collaborative effort with bass, guitars and drums all recorded remotely by the individual players. Keys and vocals were later recorded at Obie's Sanctuary III studio where he also mixed.

The track features Katie Barbato on Lead vocals through a new RTB preamp, and Rondo on (4) acoustic guitar tracks all recorded through a 2004 Revolution Recording (John Hinson) Redd.47 preamp (RTB inspiration).

Pultec pushing 3k on electric guitars. 1968 335. Speed Shop Tweed Deluxe, no effects, no pedals, no delays. Abbey Road Drums. Many thanks to Tony Reyes for his great vocal performance. (Tony recorded his vocal tracks in his studio and the files were imported.)


In your face acoustic guitars. Martin OM-28 Marquis and Taylor 514c. Adding some top on both.

Everything on this track is in the box except for the acoustic guitars, electric guitars and bass. On acoustics, some 8k was added with lows rolled off a bit. For electrics, a heavy 10k boost was applied. For bass, 5k was cut while boosting and cutting 20hz each about mid-way. Bass was hit hard through an old Ashly SC-50 limiter, as were the acoustic and electric guitars through an La2a. Redd 47 preamp on acoustics, La2a as preamp on electrics; bass guitar was though RecPro Audio Valve DI.


This is a quick rhythm track. Acoustic and electric guitars, bass, drums and a little keyboard padding. My usual acoustic guitar EQ - rolling off some 20hz and boosting highs (maybe 16k here) for a really crisp tone.


This is a quick, one-take Martin acoustic fingerstyle bit with a little reverb and a shaker. One guitar, 2 mics, a little EQ on the top end.


Guitar Rock. EQP-1a on all guitars for tone shaping.


Rhythm guitars are a Strat through a RecPro Audio Valve DI. Solo guitars are a Gibson 335 and Tweed Deluxe. Fender Jazz Bass through RecPro Audio Valve DI. Pultec EQ is on all guitars. 2 Mix was sent through a pair of Pultecs adding some 100hz and 12k.
