Shopping in guitars basses can mean very different things: a full bass instrument, a recording setup for capturing music, or a small electronics part for modifying a guitar. The right choice depends less on the category name and more on the job you need done. Among these four picks, the main decision is whether you want a playable ESP bass, a Fender Studio production bundle, or CTS potentiometers for a control-cavity project.
Quick take
- Best fit for a complete recording setup: Fender Studio Quantum Complete Bundle, because it combines an audio interface, studio monitors, a condenser microphone, and software in one package.
- Best fit for a guitar electronics part: CTS Audio Taper Pro Guitar Control Pots, Split Shaft, 250K-ohm (CTS #450S, because it is specifically listed as potentiometers with a split shaft and 250K-ohm rating.
- Best fit for a used 4-string ESP bass: Excellent ESP LTD D-4 4-String Bass Guitar, Roasted Jatoba Fingerboard, Black Na, because it is a right-handed electric bass with Black Natural Burst Satin styling and a jatoba fretboard.
- Best fit for Pelham Blue ESP styling: ESP LTD AP-4 Pelham Blue Electric Bass Guitar AP4 AP 4 - B-Stock, because the title and attributes center on the AP-4 model, solid body, and Pelham Blue finish.
Listed price comparison
The listed prices span from USD 35.70 to USD 795.00, so the lowest-priced item is about 96% below the highest-priced one. That spread is mostly because one item is a small control component, while two are bass guitars and one is a recording bundle.

Decision matrix
Choose by what you are trying to solve
- Need to record music rather than buy another instrument: Go first to the Fender Studio Quantum Complete Bundle. Its package is built around a USB-C audio interface, Eris 3.5 studio monitors, an M7 MKII condenser microphone, and Fender Studio Pro software.
- Need a guitar control replacement or mod part: The CTS Audio Taper Pro Guitar Control Pots are the focused choice. They are listed as potentiometers and include hardware such as a flat washer, lock washer, and hex mounting nuts.
- Need a 4-string bass with neck-through construction: The Excellent ESP LTD D-4 4-String Bass Guitar points toward a more detailed bass spec set, including a 7-piece maple/jatoba neck, 24 frets, HH pickup configuration, and Black Natural Burst Satin finish.
- Need the AP-4 model in Pelham Blue: The ESP LTD AP-4 Pelham Blue Electric Bass Guitar AP4 AP 4 - B-Stock is the direct match, with Model AP-4, right-handed orientation, solid body, 21 frets, and Pelham Blue body color.
Choose by condition
Condition matters here because the group mixes new, used, and open-box items. The Fender Studio bundle and CTS pots are marked New, which makes them straightforward if you want an unused studio package or electronics component. The ESP LTD D-4 is marked Used and specifically mentions light damage with minor scratch marks on the top and bottom sides. The ESP LTD AP-4 is marked Open box and carries B-Stock wording in the title, with a possible cosmetic blemish noted in the description.
Choose by instrument versus accessory
The ESP LTD D-4 and ESP LTD AP-4 are the only full bass guitars in this set. The Fender Studio Quantum Complete Bundle belongs more to a recording desk than a guitar stand, and the CTS control pots are a component rather than something you play by itself. If your immediate goal is to make sound with a bass, focus on the ESP options. If your goal is to capture, monitor, or produce audio, the Fender Studio bundle is the more relevant package. If your goal is a control electronics change, the CTS set is the narrowest match.
Concise product notes
Fender Studio Quantum Complete Bundle
The Fender Studio Quantum Complete Bundle is the broadest creative package here, built for someone assembling a recording setup around a computer. The description names a Fender Studio Quantum LT 2 audio interface, Eris 3.5 studio monitors, an M7 MKII condenser microphone, and Fender Studio Pro software, so its appeal is the all-in-one production angle rather than a single instrument purchase. Its limitation is just as important: despite sitting in a guitars basses shopping set, it is not a guitar or bass. If you are trying to buy a playable bass, this bundle solves the wrong problem.
CTS Audio Taper Pro Guitar Control Pots, Split Shaft, 250K-ohm (CTS #450S
The CTS Audio Taper Pro Guitar Control Pots are the specialist pick for a guitar control project. The title calls out split shaft and 250K-ohm, while the attributes identify the type as potentiometers. The description adds audio taper behavior, a fine-knurled 24-spline knob fit, and included washer and nut hardware, making it a focused electronics component for players or repair-minded shoppers. The tradeoff is that it is only a part. It will not help someone looking for a new bass, a recording interface, monitors, or a complete instrument setup.
Excellent ESP LTD D-4 4-String Bass Guitar, Roasted Jatoba Fingerboard, Black Na
The Excellent ESP LTD D-4 4-String Bass Guitar is the lower-priced of the two full ESP basses in this comparison and is centered on a 4-string, right-handed electric bass format. Its appeal is the detailed bass specification: Black Natural Burst Satin body color, mahogany body material, jatoba fretboard material, 24 frets, and neck-through construction in the description. It also names ESP Designed pickups and an active 3-band EQ. The limitation is condition-related. It is marked used, and the description mentions light damage with minor scratch marks on the top and bottom sides.
ESP LTD AP-4 Pelham Blue Electric Bass Guitar AP4 AP 4 - B-Stock
The ESP LTD AP-4 Pelham Blue Electric Bass Guitar is the most direct choice if the AP-4 model and Pelham Blue finish are the draw. It is a right-handed, solid-body electric bass with an alder body, maple neck, Macassar ebony fingerboard, 21 extra-jumbo frets, Grover tuners, Babicz FCH-4 bridge, and active EMG P and LJ pickups named in the description. It is also the highest-priced item in this set. The limitation is the B-Stock and open-box positioning: the description says it may have a cosmetic blemish, so shoppers focused on condition should weigh that against the AP-4 feature set.
Final recommendation
For most shoppers, the cleanest way to decide is to separate instrument, recording setup, and component.
If you want a bass guitar and are choosing between the two ESP options, start with the Excellent ESP LTD D-4 4-String Bass Guitar if the used condition and noted minor scratches are acceptable in exchange for the lower listed bass price of USD 645.24. Its 4-string format, roasted jatoba fingerboard reference in the title, Black Natural Burst Satin color, and neck-through bass description make it a strong fit for shoppers focused on the instrument itself.
Choose the ESP LTD AP-4 Pelham Blue Electric Bass Guitar AP4 AP 4 - B-Stock if you specifically want the AP-4 model, Pelham Blue body color, right-handed solid-body layout, and the active pickup setup described for that bass. At USD 795.00, it sits at the top of the group, so the reason to pick it should be the exact AP-4 feature and finish combination rather than simply wanting any bass.
Pick the Fender Studio Quantum Complete Bundle when the goal is making and monitoring recordings, not buying a bass. At USD 349.99, it occupies the middle of the spread and bundles several production pieces around an audio interface and software. Pick the CTS Audio Taper Pro Guitar Control Pots only when you need the 250K-ohm split-shaft potentiometer role. At USD 35.70, it is the lowest-priced item, but it is also the narrowest-purpose product in the group.
