The BSM RMG is a clean booster, the custom model for the typical "jingle jangle" Roger McGuinn sound of the 1960s, and the maker describes it as the perfect booster for all clean sounds123. It is a signature model based on the original V*X Treble Booster, modified to produce that clean jangle4.
What it does
The RMG runs at almost unity gain, meaning it is not designed to push an amp into overdrive but to shape the tone at roughly the same volume. BSM positions it as the perfect booster for clean, sparkling sounds such as country, as well as for acoustic guitars4.
"For the classical clean "jingle jangle" sound at almost unity gain, the BSM RMG is the perfect pedal."
Where it sits in the BSM family
BSM's 2019 spec sheet for the VX family describes the RMG as another sibling of the BSM VX-C, the custom model for the McGuinn sound3. Compared with the VT-B, which has preset shimmering highs, the RMG has a pot to fine-tune the high end4.
| Model | What it is | High end |
|---|---|---|
| RMG | Custom model for the Roger McGuinn "jingle jangle" sound | A pot to fine-tune the high end4 |
| VT-B | Sibling booster in the family | Preset shimmering highs4 |
| VX-C | Clean treble bass booster, sibling of the RMG | Per the VX family spec sheet3 |
The RMG is a signature model, not a general-purpose booster: it is based on the original V*X Treble Booster and modified specifically to produce the clean McGuinn jangle4.
What reviewers said
Premier Guitar's press release on BSM's boosters, announcing the line, put it this way: "BSM is bringing you the late sixties in a box"6. The same release noted a practical use: "With a compressor, the RMG can also make any standard Strat sound like a Tele"6.
