Both kits are designed for beginners but offer different features that may appeal to various users. With JupiterForce ranking 22,919 in sales and RockJam at 23,779, both products have established themselves in the market, but the JupiterForce may attract slightly more attention based on its sales rank.
Build Quality and Design
The JupiterForce features a high-quality all-wood construction aimed at providing durability and a comfortable grip, making it ideal for beginners and aspiring musicians. In contrast, the RockJam boasts a full-sized basswood body, which is known for delivering rich sound quality. The ergonomic ST design of the RockJam, along with its high-gloss finish, offers a professional appearance that may appeal to users looking for aesthetics as well as functionality. Both guitars are designed to cater to different preferences in playability and style.
Sound Quality
Sound is crucial for any electric guitar, and both kits deliver impressive audio performance. The JupiterForce uses high-quality steel strings to provide a crisp tone, making it suitable for various musical genres. Meanwhile, the RockJam features three single-coil pickups, allowing for a broader range of sound customization. Its amplifier includes tone and gain controls, offering more versatility for users seeking to experiment with their sound. While both guitars provide good sound quality, the RockJam's additional features may offer more for those looking to fine-tune their sound.
Accessories Included
The accessories included in each kit provide added value for beginners. The JupiterForce kit comes complete with a 10-watt amplifier, guitar strap, cable, additional strings, picks, and even a tremolo rod. The RockJam kit offers similar essentials, including a 10-watt amplifier, gig bag, picks, spare strings, and access to online lessons. While both kits are comprehensive, the RockJam's inclusion of educational resources could be particularly beneficial for new players looking to learn quickly.
Portability
When it comes to portability, both kits include bags to transport the guitars. The JupiterForce comes with a nylon bag that allows for easy transport to lessons or gigs. The RockJam, however, features a gig bag designed with 5mm padding for extra protection, making it a more secure option for traveling musicians. The RockJam's additional padding may offer peace of mind for users who frequently move their gear.
Target Audience
Both kits are tailored for beginners, but they also have features that could appeal to intermediate players. The JupiterForce, with its simple design and quality construction, is perfect for young aspiring musicians who are just starting. On the other hand, the RockJam’s additional controls and online learning resources make it suitable for users who may wish to explore a variety of musical styles. Each kit serves its purpose well, but the RockJam may provide a slight edge for those eager to learn and expand their skills.
Price Comparison
With the JupiterForce priced at $104.98 and the RockJam at $101.99, the RockJam offers a savings of approximately $2.99, making it about 3% cheaper. This small price difference may influence budget-conscious buyers, especially those who are just starting and may not want to invest too heavily. The RockJam's price point, combined with its wide range of features, could make it a more attractive option for those looking to maximize their investment.
Which should you buy?
Both the JupiterForce 39 Inch Full Size Electric Guitar Kit and the RockJam Electric Guitar Kit offer excellent options for beginners, each with unique advantages. The JupiterForce excels in build quality and sound clarity, while the RockJam provides a slightly lower price and additional features like online lessons and customizable sound controls.
