Shopping in guitars basses can get confusing fast because the products often solve completely different problems. A vocal processor, a Les Paul prewired kit, a bass speaker, and a rack compressor may all sit near the same music-gear aisle, but they belong in different signal-chain decisions. Start by deciding whether you need sound processing, an electric-guitar electronics upgrade, a replacement or project speaker, or dynamics control for guitar, bass, or pro audio.
Quick take
- BOSS VE-22 Vocal Performer Multi-Effects Processor 50 Presets PRO is the pick here for vocal effects, with digital multi-effects, pitch correction, harmony, doubling, XLR connections, 50 presets, and 99 memories.
- Prewired Guitar Kit Les Paul Long Shaft Pots Gibson Orange Drop Caps Switch is the practical choice for a Les Paul-style electric guitar electronics upgrade, especially if long shaft pots and Orange Drop caps are the target.
- Eminence LEGEND BP 122 12\" 8ohm Pro Audio Bass Guitar Speaker 500W 2 in VC is aimed at speaker projects needing a 12-inch, 8-ohm bass guitar driver with pro audio and home hi-fi use also named in the product description.
- DBX 160X Compressor/Limiter Professional Guitar Bass Pro Audio is the dynamics option, with compression/limiting, noise gating/expansion, rack-mountable form factor, and sidechain insert called out.
Listed price comparison
The listed range runs from USD 108.99 to USD 384.99, with the lowest listed item sitting about 72% below the highest listed item. That spread matters because the lowest-priced item is a guitar wiring kit, while the highest-priced item is a full vocal effects processor; the prices are not just different tiers of the same product type.

Concise product notes
BOSS VE-22 Vocal Performer Multi-Effects Processor 50 Presets PRO
The BOSS VE-22 is the most clearly performance-oriented processor in this group. It is built around digital vocal processing, with tools such as compressor, EQ, delay, echo, reverb, pitch correction, harmony, doubling, and more stylized effects including lo-fi, distortion, and radio-style sounds. The 50 ready-to-go presets and 99 memories make it especially relevant if you want a vocal effects unit rather than guitar hardware. Its limitation is just as important: the listed fit is vocal processor, so it is not the right answer if your immediate need is a Les Paul wiring kit, a replacement bass speaker, or a rack compressor.
Prewired Guitar Kit Les Paul Long Shaft Pots Gibson Orange Drop Caps Switch
This kit is the narrowest, most guitar-specific choice. It is described for USA Gibson Les Paul models made from 1977 to present using long shaft pots, and the package centers on 50s wiring, Bourns Pro Audio 500K long shaft coarse spline audio taper pots, Orange Drop .022uf bridge and neck tone caps, Gavitt wire, a 3-way toggle switch, and a 1/4-inch jack. Choose it when the job is electric-guitar electronics rather than signal processing. The limitation is its specificity: it is a Les Paul Prewired Upgrade with long shaft pots, so it is not a general-purpose processor, speaker, or compressor.
Eminence LEGEND BP 122 12\" 8ohm Pro Audio Bass Guitar Speaker 500W 2 in VC
The Eminence LEGEND BP 122 is the speaker-focused item. It is a 12-inch bass guitar driver with 8-ohm nominal impedance, 500W program power, 250W watts rating, 35 Hz resonance, 35 Hz to 2.3 kHz usable frequency range, and a 2-inch voice coil. The description also names small sealed enclosures, pro audio, and home hi-fi applications, making it the obvious starting point for a speaker-based project among these four. Its limitation is that it is a driver, not a finished effects unit or guitar control assembly; shoppers wanting knobs, presets, compression controls, or Les Paul wiring hardware should look elsewhere in this set.
DBX 160X Compressor/Limiter Professional Guitar Bass Pro Audio
The DBX 160X is the dynamics-control entry, and it stands apart from the BOSS unit because its named effects are compression/limiting plus noise gating/expansion rather than vocal harmony or pitch features. It is also marked as rack mountable, with active operation, sidechain insert, and 6.35 mm 1/4-inch TRS/TS input/output ports. That makes it a focused option for guitar, bass, or pro audio signal control where compression and limiting are the priority. The tradeoff is condition and scope: it is listed as Used, and it is not presented as a multi-effects vocal unit, a speaker, or a Les Paul electronics kit.
Final recommendation
For the broadest effects feature set, choose the BOSS VE-22 Vocal Performer Multi-Effects Processor 50 Presets PRO at USD 384.99 if your setup centers on vocals and you want presets, memories, pitch correction, harmony, doubling, and XLR connectivity in one unit.
For the lowest listed spend in this group, choose the Prewired Guitar Kit Les Paul Long Shaft Pots Gibson Orange Drop Caps Switch at USD 108.99 when the task is specifically an electric-guitar Les Paul prewired upgrade with long shaft pots and Orange Drop caps.
For a bass speaker build or replacement-style project, the Eminence LEGEND BP 122 12\" 8ohm Pro Audio Bass Guitar Speaker 500W 2 in VC is the most directly matched product because its title and specifications revolve around a 12-inch, 8-ohm bass guitar speaker.
For rack-style dynamics processing, the DBX 160X Compressor/Limiter Professional Guitar Bass Pro Audio is the clearer fit than the other three because compression/limiting, noise gating/expansion, sidechain insert, and rack-mountable form factor are all central to its description.
